Sorry for the double post (and both ludicrously overlong) but I thought I should answer and this was a more convenient format.
Incidentally, regarding the Chakotay spiritualism discussion I agree that his early portrayal left a lot to be desired. Whether or not you regard it as racist seems more a matter of semantics. It was a clear example of reductive stereotyping which personally I found embarrasing. It really was space injun by numbers. I groan whenever he starts wheeling out his spirit guide. I thought he was much better portrayed later as an enlightened, sophisticated, scholarly man of reason and compromise, ying to the captain's yang, the antithesis of the terrorist stereotype, and distanced from the earlier guff.
Mind you, I'm glad I didn't see any of Voyager until season 3 originally as I'd probably have hated it otherwise. There's lots of great stuff in the first two seasons but as a whole the concept was weak and the presentation of it lacked punch or distinctiveness. Saying that, the first two of TNG were much worse but I didn't see them originally either, praise the lord.
And I found VOY largely stayed away from having imaginative twists on Sci-Fi staples, but out of interests what interesting twists did you spot?
That’s rather a big question to have to answer. I suppose the normal two responses are to either refuse to answer and appear to have taken my ball and gone home to sulk or to give five or six examples which you proceed to dissect and show how much better than mine your taste is. I'm afraid I'm going to do neither and if you'll have to work for it if you want to demolish my position.
I’ve done my best to provide a range here from what I can remember by scrolling through the episode list, although it's rather meandering. This is not an indication of quality –some of the eps mentioned here are actually awful. The point is that, at least in the context of mainstream televisual sci-fi, or of Star Trek itself, these ideas strike me as being interesting twists on the usual or as worthwhile developments within the franchise and are, I believe, indicative of this being a general trend in Voyager. Many of these my response to was ‘Why didn’t anyone think of doing this before?’. Anyway, enjoy –no doubt you’ll be glad you asked...
For those who haven't watched the series or are in the process of doing so there are tons of SPOILERS here so stop reading now.
The Kazon: Major enemy who is technologically backward and not on an equal footing with the heroes. Totally different to any prior ‘ongoing’ villains in Trek. This is particularly nicely developed in State of Flux where ‘simple’ replicator tech which viewers take for granted has horrifying consequences.
Phage: The Vidians are an alien race that are truly monstrous bad guys yet they have real, sympathetic motivation. It’s hard to deny that any race faced with such a situation would probably do the same if they had the means. This is utterly unlike anything in the Trek universe before which is populated by a range of baddies comprising space Nazis, space commies, space pirates and comedy capitalists.
The Vidians were one of several new alien species that had strong concepts and good designs which were created for Voyager. Species 8472, the Hirogen, the Malon, the Hierarchy, and perhaps the Vaadwaur are also worthy of mention. I’d say that TNG only produced the Borg (and perhaps the Trills but I think the concept was successful here but offered nothing in terms of design). As for DS9 I’d say that only the Vorta and the Jem’Hadar qualify.
Faces: Genetic splicing of a character into two distinct halves. Original play on the ‘warring nature’ trope.
Jetrel: Mass murderer portrayed sympathetically.
Prototype: starts off down the well trodden road of empathy with a different form of life/consciousness only for the lead’s heroic actions turn out to be utterly misguided as the creature turns out to be a genocidal lunatic. This theme of the potential and the dangers of artificial intelligences is played on repeatedly throughout the series sometimes positively and sometimes far from it. On the negative side we might consider Dreadnought, Revulsion, the Doctor being reprogrammed in Equinox, Warhead, and even the troubling implications of Renaissance Man. Where TNG would’ve had a rousing affirmal of Data’s rights as a sentient being Voyager answered with a much more troubling half hearted ceding of very limited rights in Author, Author.
Threshold:
Meld: I don’t see any question that this is easily the most original approach to mind melds in Trek history. Having Tuvok suffer the consequences of a meld with a psychotic was a brilliant idea. Also, the fact that one of the permanent crew who is a recurring character for a while was a psychotic murderer. That in itself is a totally fresh idea in Star Trek.
Death Wish: Star Trek’s obsession with omnipotent beings is back again; but this time with a very different approach. The idea of an omnipotent being wanting to kill itself to end the boredom of its unending existence is totally unprecedented in Star Trek which was ideologically more profound than any prior Q episode. The later appearances of Q in Voyager would almost match it for originality and genuine thought provocation too.
Tuvix: An excellent and original ‘transporter accident’ ep ex[ploring a strong central concept. Stands as one of the definitive examples of the genre and presented an excellent moral dilemma.
The Swarm: pres4ents aliens who are totally alien both socially and in their environment. Utterly resistant to communication and diplomacy of the TNG committee style.
Future’s End: Voyager is of course infamous for its time travel, causality paradoxes and for its use ofthe reset button. They’re all here. They’d already done one where the heroes’ well intentioned meddling actually causes the disaster they were trying to prevent and results in a paradox. This time its a similar approach save that the results of the intervention are less direct –they set in motion the events leading to the disaster and the paradox and its the actions of a ‘professional’ time traveller and the potential multiple futures they could have come from that underpins their motivation causing the whole thing. Running through all of these paradoxes would take up too much space but most are inventive and entertaining and often provide opportunities to tell stories you’d otherwise be unable to tell in an ongoing series. Steven Moffat’s Doctor Who has taken up the baton and gone much further with this stuff but it was Voyager that laid down the gauntlet.
Blood Fever: Excellent Vulcan episode combining Pon farr and mind melds to new, amd of course logical, effect. Its influence is detectable in one of Enterprise’s better episodes too.
Unity: Best take on the ‘post Borg’ on a mass scale. So much better than ‘IBorg’ and undoing much of its damage. Exploration of the horror of the collective consciousness but also the allure of its power and the temptation for abuse. Makes an ‘origin of the Borg’ story pretty redundant –it’s all here.
Favoriet Son: Harry Kim has a rather delightful tendency to find himself in a Buck Rogers storyline. This time the Amazon Women really are going to mate with you but then they’re going to kill you. Blast that planet of the spider women!
Worst Case Scenario: Easily the best example of the most hated type of Star Trek episode. This is the only one that’s actually essential viewing. So many good ideas in its play on the genre that it’s like a Russian doll. It’s outstanding the way that all the motivations and behaviour all tally at each level of the plot, and is simultaneously satirical. Tight as hell.
Scorpion:
Alliance with the Borg. Real interaction with a collective consciousness rather than the bullshit Queen from First Contact (don’t get me wrong, I understand the need for the Queen in terms of dramatic necessity for repeated use of the Borg but the Collective is still a purer and better representation and this is probably the most in depth look at it we ever got. It actually had to make tough decisions rather than just be so unbeatable that any discussion is, er, futile).
Also, the Captain is wrong. She’s so bullheaded that she’ll get everyone killed. Chakotay saves the day with his back up plan. Picard would never do this. He’s always right and always noble (like the way he can never lose the ship –if the Enterprise goes down it’s always Riker in charge...). The only exception for Picard is the Borg. Then his judgement is thrown and he can behave ignobly. The same is true with Sisko –it’s Picard and the loss of his wife that will set him down the wrong path. These are Achilles heels. The difference is that it’s a genuine character flaw with Janeway rather than a particular trigger, and her weakness is also her strength. We see it again in Year of Hell –Janeway’s stubbornness and total belief in herself leads to huge loss of life and the crew having to abandon ship. This is something new in Star Trek.
The Gift: Character’s telepathic abilities evolve to a point where they can no longer coexist with physical beings bound to this plane of existence.
Day of Honour: Warp core ejection has since become a staple of the franchise but was first done in Voyager. This is probably the best example where one of their attempts to incorporate alien tech to go faster backfires badly. It’s become a significant trope of the whole conception of the dramatic iconography of the Engineering section in Trek.
Nemesis: Decent take on the ‘get involved in the hoopla on the planet’ type with psychotropic brainwashing recruitment. Nice to see the ugly monsters as the good guys for a change too.
Scientific Method: There are a series of species encounters ‘on the go’ with aliens that have evolved unusual natural defences or have very distinctive methods. This si one of my favourites. Calling into question the morality of science in the RW and even that of our heroes. Some other examples are the aliens who conquer with substitution, the sleeping aliens, aliens who can’t be remembered,
The Omega Directive: Great tribute to classic Trek but with excellent use of the Borg as a counterpoint perspective on the directive.
Random Thoughts: Telepathic backwash? Criminal justice applied to it?
Living Witness: Use of artificial intelligence’s ‘immortality’ in an examination of the notion of historical truth.
Demon: Taking the exploration angle to an environment that would normally be overlooked. At last, not another M class world. Similarly Night has them traversing an area where there’s just nothing for an extended period. It’s against type but presents opportunities.
In the Flesh: Ace take on old Soviet style spy training towns.
Timeless: Back From the Future! Our heroes saved from certain death by their future selves.
Thirty Days: Leading character breaks the rules and is demoted (for a long time).
Gravity and Blink of an Eye: Both inventive takes on time moving at different relative speeds.
Bliss: Take on the sirens with interstellar predator.
Dark Frontier: The Hansens as scientists acting outside of Starfleet seen in practice. Good bit of bubble bursting.
Course Oblivion: By this time the show was often playing on itself. This was one of the best examples and a superb surprise.
Alice: Symbiotic spacecraft, malign influence of telepathic interface.
Dragon’s Teeth: Strong premise of army in suspended animation. No doubt some will point to Khan but that’d be missing a lot. This is a civilization saved for the future not imprisoned. The heroes, following the initial accident, wake them up as allies only to discover their mistake.
The Voyager Conspiracy: Could hardly be targeted more at the audience and its perceived tendency to overlap with the conspiracy nut demographic.
Virtuoso: Alien society that’s never experienced music.
Memorial: Innovative take on the idea of a war memorial.
Ashes to Ashes: Procreation through the reanimation of the dead.
Child’s Play: Viral warfare against the Borg. Obviously a play on ‘I Borg’, and perhaps ‘Descent’ too, but this is so much darker with a race so desperate that they are sacrificing their children.
Live Fast and Prosper: Hilarious satire of Federation nobility. If you can’t laugh at yourself...
Unimatrix Zero: Hypothesizing dream state in collective consciousness. Excellent new angle on the Borg.
Repression: The Maquis taking over the ship had always seemed like a likely plot to occur in Voyager in the early days. It finally happened when there appeared to be no chance of it ever happening.
Critical Care: Laboured essay against Obamacare (or the NHS for those of us in the more civilized parts of the world...) also explores the potential for slavery of AI’s.
Body and Soul: AIs and cybernetics in slapstick hi-jinks.
Flesh and Blood: Logical progression from earlier story sees misuse of donated tech. Prime Directive actually looks sensible for once.
Prophecy: Klingon religious nuts. One of them even appears to be a reasonable person rather than the usual caricature. Batleths still appear to be the most impractical weapon ever devised though. Paris really should have looked into the possibility of being allowed to use a sword against one of the idiot Klingons –he’s have cut him to ribbons.
Workforce: great sci-fi labour shortage idea.
Friendship One: Decent idea for pro-Prime Directive narrative. Tragic death of likeable minor character nudged audience towards weighing the moral balance of the story (not relevant to what I’m talking about here but I just thought I’d mention it as it upset many –I think it carried storytelling weight).
