NB - spoilers for this show feature in this review

Dedicated viewers of this new fantasy/action-adventure show will receive some nice development and twists in relation to the main story of this opening season. However problems of inconsistency and homogenous settings and set pieces are never far away -even in those episodes which reach higher quality than any of the opening half dozen.

I might as well make clear that I don't think Jack Donnelly is being used well - and by that I mean that he would be a serviceable secondary character for some other prime time TV show, or by the same token certainly watchable in a cinema released British rom-com. There are elements where he shines when he looks just a bit comical and helpless and his pretty boy looks would work well with a strong leading lady to complement him. But even with the best scripts that this writing and production team put on the table, we have a lead hero in Jason that seems to work in reminding us how low-key fantasy shows can be. If done by the numbers one story in this genre can very much resemble another. If the characters all come out with dialogue that seems labored and pre-meditated then the suspension of disbelief most viewers are required to apply just wiill not be there, due to their grounding in realistic drama elsewhere.

This show continues to invest in some fine guest stars. Amongst experienced character actors such as Fintan McKeown, Anton Lesser and David Stern, there is good work from Gemma Jones and Jason Watkins, plus some showcases of more fledgling talent like Nora-Jane Noone and Will Merrick. Many casual viewers will be quick to recognise and enjoy the efforts of widely known favourites of stage and/or screen - Robert Linsday Julian Glover and John Hannah. Just in terms of investing in acting chops, the producers are doing a fine job and may be able to build a good solid audience that have different people coming back each week for different reasons.

But it is almost then trying to be bold enough to say - "here is the license payers money to show you who we can set up a contract with.. But just enjoy the antics of the main actors -- after all they are the ones who flash on the screen at the start and end of the show. What, you want some proper development of these new character? Even if they are one-offs? Sorry, try another channel altogether'. Now I seriously doubt this experienced team who have helmed Merlin and Misfits would really want to convey such a message. But in the process of executing their work duties, they nonetheless manage to look a gift shop horse in the mouth.

Thankfully however the better regulars seem to be going from strength to strength. Pythagoras is shown to have a very dark side in relation to troubled family relations, and Robert Emms belatedly does more than just turn in an OK or respectable portrayal.. I am left hoping that he plays a more proactive role in the upcoming second season - and perhaps he will develop his acting style organically in the process. Whilst I enjoyed Will Merrick in 'Skins', I found that when called upon to be gritty and troubled as Aracas - brother to Pythagoras - rather than hapless that the actor didn't quite have the range needed. I would be happy to be proved wrong in a potential reappearance next year though, as the seeds for a good character driven storyline were sown despite the overall episode (the Furies) being less than totally successful.

Also the amiable cuddly Hercules is shown to have less than noble qualities in his determined chase of Medusa. Something that a cynic might say almost deserves the tragic twist in these two characters dynamic come episodes 9 and 10. Much buildup and character development was given over to this strong female character, who continues to be portrayed with skill and charm by Jemima Rooper. The investment the regular audience has put into this secondary lead is rewarded handsomely/. And the buffoonish Hercules is now someone to be concerned for, rather than just to laugh at and root for in a light-hearted fashion.

Which makes the generic and frustratingly slow-to-learn Jason all the more startling and difficult to comprehend. His reaction to his friends' plight, along with his development as a fighter and a quick thinker should mean there is a growth in the audiences' journey with him as he becomes a tried-and-tested Atlantean resident. Yet the mirage of believing that this is a fully-fleshed person and not a character issued with some hard-and-fast traits essentially dwindles and instead the viewer can only grasp the proportions of a forced caricature.

But the show arguably save the best for last, and in a fashion suggesting that the opening season could be shrugged off as 'growing pains' in several years time as the BBC have another big hitter. The two-part finale makes up for the rather weak eighth and eleventh episodes, and build on the sold if unspectacular episodes that realign Medusa's role is in the general scheme of things. Episode 7 is certainly the best stand alone episode of the 1st season until the finale. If such an episode became the norm and perhaps some more multi parters were used, then the show could show enough versatility to make more use of its latent potential. I hope the creative team are somewhere in a meeting coming up with better storylines that fulfil the perennial 'beginning-middle-and end' recipe for success, without being overly conventional and safe.

'Touched by the Gods' deals with some 'dead wood' that might still be of interest for a number of future episodes - i.e. evil witch Circe and Heptarian but which drama and excitement justifies.. And the twist with Pasipahes' tie to Jason may not be totally shocking but promises some fun conflicts of interest, with deep emotions clashing with pre-conceived and ruthless plans for power

My thoughts on the production values, music and other similar aspects have not changed. This is in large part due to the convention of serial show like this heavily re-using resources from episode to episode. At the end of the day the scripts and performances matter to me, being a British viewer of a home-grown show, and other elements have been perhaps less pressing - certainly when it came to watching archive TV like Doctor Who, Blake's 7 and Randall and Hopkirk. If the core of a show is strong and dynamic usually other departments 'raise their game'. At the time of writing I can only hope that someone or a group of people have turned a corner and convinced the overall cast and crew that this show is not just salvageable but actually a great treasure trove of wonder, mystery and court intrigue. In short tea-time adventures that engage the under 12s, the over 65s, and the in-betweeners in equal measure .

This latest fantasy fare that went out in Autumn on BBC1's Saturday line-up is the work of Merlin’s Julian Murphy and Johnny Capps, and Misfits’ Howard Overman. Much like past BBC shows such as Merlin and Robin Hood the underlying objective is to pay homage to well-known and perennial myths, tales and legends. With a contemporary feel that intends to engage the audience with the onscreen characters , the show is also trying to retain the special, classical nature that the old stories have.

The first aspect which I wish to highlight is the strength of the show's premise. Now in some ways the solid credentials of the production/writing team would make you expect a better sense of direction for a new show than perhaps would be the case otherwise. For myself anyway the core idea of Atlantis is not fully clear or used to its actual potential. The very beginning opens in modern times as Jason (newcomer Jack Donnelly) - in every way a 21st century Englishman - goes looking in the ocean hoping to resolve the mystery of his father's disappearance. Eventually he finds a wreck underwater called 'the Oracle' then wakes up without his modern clothes in the fabled lost city of Atlantis. He quickly acquires the more modest attire of the ancient times and sets about establishing a new home and identity for himself.

There is a lack of clarity over the nature of Jason - is he an explorer from another dimension or really the bona fide Jason of Greek lore? This could have been a clever and exciting character arc but just does not go anywhere meaningful for much of the opening run. Jason is from our time and knows the essentials of Atlantis lore so is in some ways is at an advantage by being so aware of what might/should happen. Yet this is seemingly dropped in favour of a lead who is totally comfortable and familiar with his surroundings by the end of the episode.

In terms of the actual actors and the characters they are given, the show has mixed fortunes. Mark Addy plays Hercules and is back in more familiar territory as the comic relief, after his excellent dramatic performance of King Robert in Game of Thrones. No matter how lacking a storyline may be, Addy can be called upon to liven things up without needing to chew the scenary. Many moments involve Hercules coming out and stealing the scene. For despite being fat, alcoholic and slovenly he seems to be the heart and soul of the show.

Of course apart from Jason and Hercules there is a need for a third character to provide an interesting dynamic. Joining the 'man of action', and the 'past-it rogue' is the 'brains', or Pythagoras - adept at plans and anything remotely complex in mathematics. Played by Robert Emms, this regular cast member is decent enough to watch but rather inoffensive and thus bland when compared to other players. I struggle to remember notable dialogue that he happens to utter, such is the often lacklustre nature of the scripts when it comes to decent characterisation.

Jason is sadly rather weak - the inexperience of the actor being exposed -and relies on better performers around him to make his scenes work. This is especially glaring if the viewer were to compare this show directly with episodes of Merlin - with the excellent Colin Morgan. Even Robin Hood had an agreeable man in Jonas Armstrong. Thus - for the moment anyway -this trio of protagonists are not exactly likely to be the topic that people will be talking about when bringing up their television experiences of the recent weekend.

When looking at characters who appear on a recurring basis, there is more satisfaction to be gained. The Oracle, in a clever link to Jason going down to a wreckage of the same name in the opening sequences, is spookily and mysteriously conveyed by Juliet Stevenson. Even better is the wicked queen Pasiphae. Sarah Parish has done the villainess multiple times before on-screen and is reliably strong. These two actresses certainly know their craft and can add life to even the thinnest of material.

As for others in the royal court, King Minos (Alexander Siddig) has a striking visual presence but lacked a bit too much regal charisma for my liking. He is also somewhat conveniently made to look slow by all the politicking and scheming going on close to him. Ariadne (Aiysha Hart) the immediate heiress to the throne is probably the most average of the cast. She sports an appropriately 'Mediterranean princess' look and has some decent delivery but her scenes never transcend the forced plot developments that take places as one episode follows another. However she seems to get some more expressive reactions out of Jason such is their budding love story. Nonetheless I would prefer that the main lead was bringing a bit more magic to these important one-on-one scene. Donnelly certainly has the looks that would interest a princess, but he seems just a bit passive and unsure of himself.

Elsewhere in the cast, Medusa is very well played by Jemima Rooper as a girl next door with some real courage. In a welcome example of good character interaction, she brings out the best, most meaningful aspects of Hercules. Anticipating her inevitable tragic fate does evoke some bittersweet emotions almost immediately, as the viewer must accept that her capacity for good is to ultimately be subverted for great evil. For those looking for female characters to be proactive and relatively independent, Atlantis builds on the fine examples that Merlin set. Medusa is often needed for help, rescue or just some sage advice.

Another good supporting player that more than looks the part is Oliver Walker as Heptarian. He is just one notch down from the supremely wicked queen in the 'despicable enemy' league, and is a worthy combatant and thorn in the side for the main heroes. Yet even this positive is tainted by the impression that Walker would have probably done a better job than Donnelly as Jason.

In terms of other strengths, there is much soundness in the production values. The show is often lit in bright sunshine such is the warm island setting, or shrouded in atmospheric darkness due to night time or events in unknown caves. Many viewers can pick up on an overall atmosphere that is breezy and mild. The lack of being tied down by historical accuracy means that there is scope for some variety of story and events can proceed differently to what had long been accepted by readers of these myths. Sets and costumes are good, and most of the effects are perfectly acceptable for modern TV and don't take viewer out of the experience.

There are however arguably more weaknesses in this opening run which threaten to drag the show down into unwelcome mediocrity. For one, the potential that exists from the basic variety of stories is not fully harnessed and a lot of formulaic or clichéd stuff happens just a bit too often. Jason seems to have an alarming lack of judgement and sense of how to learn from his errors, although he is not the first protagonist to lack judgement in serial format entertainment. There is a tiresome pattern where he antagonises a guest character which leads to some form of mission, such as retrieving an item, protecting someone or ending the threat of some dangerous beast. The sense of jeopardy coming from the royal court with King Minos being an obstacle for seemingly 'right' reasons, and Pasiphae developing into a very powerful threat is key. However in the vent this supposed tension still plays out at times with a curious lack of oomph.

Although the settings and filming is decent enough there is far too much blurring or overlap, whereby it seems practically every episode has a wander through generic woods or a bit of 'stealth' under cover of darkness. Even more tiresome is the forced humour . While often funny, even Hercules can cause the viewer to cringe at times. One example being his description of a fellow prisoner as 'the man with the three wives [who] knows what I talk about'. This joke is fine for a fundamentally comic storyline, but the context of the actual episode is rather grim. And in the process it adds nothing to a one dimensional supporting character - of which there are plenty in the larger guest cast. This becomes a constant issue with the series - for a light entertainment show there is too much uncertainty just how to blend the less intense moments with the more harrowing ones and that is quite a disappointment given the creative team's past good work.

If things are not forced then they are clichéd half the time. Ariadne often clashes with Pasipahe over her transparently wicked intentions, offering barbed wit. No quarter is given or taken, but the writers certainly did not take long to throw out some tired lines more suited to a catfight in a 1980s 'supersoap'. Any opportunity to hint or provide interesting clues over just what happened with the late wife of the king and birth mother of Ariadne is rather glossed over. Minos clearly is a more modest role than Pasipahe but more could have been done to flesh out his character whether he is onscreen or not. With the lack of information, the audience is forced to fill in blanks relying on conventional step-mother/second wife tropes. There is opportunity though for this to be rectified in later episodes, but would require some care and attention from the writers.

Many BBC TV shows boast music that helps to make the show more effective Atlantis' musical dimension sadly reaches an unremarkable level. Every 'plot development' is seemingly telegraphed and the humour is often surrounded by a dirge of musical 'slapstick'. Mainly contributed by Rob Lane with some work coming from Rohan Stevenson, this is another element which can be improved upon. Perhaps more dynamic scripts would garner better creative input from the music department.

Despite all my issues in general, out of the opening six instalments, only two were real let-downs, i.e. 'A girl By Any Other Name' and 'Twist Of Fate'. The opener was intriguing and well-paced and in my opinion should be mimicked in later episodes for vibrant themes and character momentum. The third and fifth episodes are very enjoyable for the most part, with the sixth being decent enough and bringing some much needed tension as future plot developments look to be rather ominous for the kind-hearted central trio.

In summary Atlantis is arguably a show with just as much, if not more, potential than Merlin, with its options for exotic lands and a variety of human and animal foes, as well as crafty intrigue in the royal court. For now the overall hit-and-miss in terms of story quality is a big hurdle. Even the better episodes can lack depth, as the scripts often trot out average dialogue, and miss out on numerous thematic and 'moral lesson' aspects. The show feels less than the sum of its parts, as bits and bobs of Minoan civilization are pulled together and most episodes are self-contained and could be watched in different order, such is the loose season arc. For any proper momentum to be generated, this show will need more work from almost everyone concerned to match the fine efforts of Mark Addy and a few of those that provide supporting roles.
