No, there's another way for them to screw up: by contradicting the films.
They should keep the stuff from the PT that worked okay (and if any of these were actually established in the EU previously, my profuse apologies for being an ignorant Trekkie

) and scrap the stuff that didn't pan out:
Worked Okay
- The Jedi are a politically important semi-religious cabal who find and raise Force-sensitive children into a demanding and ascetic lifestyle.
- The Jedi run the military part of the Republic, and continually collaborate with the Senate, who run the political aspects.
- The Jedi are required to follow a philosophy of total detachment in order to avoid falling to the Dark Side. Their rules make sense and are not just a bizarre form of egotistical masochism.
- With rare exceptions, the Jedi don't allow marriage because that's almost impossible to pull off without attachment.
- The visuals and the music (they're doing a great job extrapolating on both).
Should be Scrapped/Details that Need to be Added
- Anakin being depicted as a weak, whiny punk. Fortunately, this has already been scrapped (yay!) - now he acts like a grown man, not a self-involved adolescent - so this depiction might have been unintentional all along.
- Padme being depicted as Useless Pregnant Girl, and having little identity beyond her relationship with Anakin (and being a dolt for having a relationship with Anakin). The revision in Anakin's depiction has solved part of this problem - I can now see how a smart, sensible lady might just "ignore" Jedi rules she doesn't value or understand to hang onto a very attractive guy - and Padme's political role in the story is being greatly expanded so that she's emerging as a central character who is helping to drive the story.
She doesn't seem nearly as powerless as she did in the movies, probably because we're seeing more of her initiating political action rather than hanging around being a target of assassins or moping around the house.
- The (perhaps also unintentional) depiction of the Clone Wars as wholly contrived by greedy capitalists and nefarious Sith, without any legitimate grievances from the Separatists. This is in the process of being scrapped (yay!) through the addition of more details to the story.
I'd like to see the legitimate Separatists being the original driving force behind the war, with the capitalists and Sith jumping on the bandwagon in an opportunistic way. This feels like a much more natural way for the war to evolve, and doesn't require the good guys to be ridiculously oblivious or naive.
- The lack of any reference to the morality of using clones as cannon fodder. As of the last episode, there are signs that this may be changing. My own favorite fanwank for addressing this problem is that the Republic isn't really a perfect analogy to our own society, because they don't have the concept that all sentient beings are equal.
We've seen artificial lifeforms like droids that seem just as smart (if not moreso) than flesh and blood beings, yet are treated as inferior. Maybe artificially-made flesh and blood beings are considered equivalent to droids, or intermediate between droids and naturally-occurring species in the Republic's social hierarchy?
I actually like the idea of the Republic being "alien" and a little creepy in this way - hey, it's sci fi after all! - but if this is what's happening, I'd like to see it spelled out.
- The character of Ahsoka is a "detail" that is turning out to be a very good addition to the story, now that the political/military saga is being personified in the conflict between Anakin and Padme (I think that's where they're going), and that conflict in turn is being personified in a tug of war over Ahsoka. As a child growing into adulthood, she represents the future, but
whose future?
Still TBD
- As long as the above continues to be expanded upon in the coming seasons, all that's left is to finally delve into more details about the Force. What does it mean exactly to "fall to the Dark Side"? How much do each of these factors play into it? a) demonic possession; b) drug addiction; c) a cold-blooded pragmatic choice (the Dark Side confers more power more easily); d) the sheer attraction of irresponsible evil; e) personality type; and f) whatever factors I may be forgetting about?
