On the other hand, Abrams' Star Trek has distinctly less spectacle than Lucas's prequel trilogy, but it's much better at handling its leads then the prequels are, which makes it a much more entertaining watch. I've seen it described as the Star Wars film the prequels weren't and I think there's a fair bit of a truth to that.
nuKirk's bad-boy-who's-a-rapidly-rising-star thing makes him a better Anakin than the Anakin we got, for one.
Well that's damning with faint praise!

And not a parallel I'd ever have thought of.
I think (hope!) Kirk is on a trajectory that is far less dramatic than Anakin needed. Kirk is just your usual sort of smartass punk. Not odious or doomed to be evil or any of that. A bit of maturity (provided by the next movie kicking him around some and making him wise up about his limitations) is all he needs.
The original Kirk was a wonderfully complicated guy, with a great deal of seriousness, sincerity and heart, along with a lot of glibness, devil-may-care-ness and even rebelliousness. He was a walking bundle of contradictions that nevertheless added up to a very believable character. Reconstructing a character of that depth is a good use for three movies and I'm rooting for them to pull it off.
Anakin is a completely different sort of fish, and as tough as Kirk might be to construct convincingly, Anakin is a character type that is rarely even attempted - a sympathetic and heroic character who the audience believes in and follows along his journey, who becomes horrifically evil, and we buy it every step of the way.
The solution is not to make him unheroic to begin with, which seemed to be the "strategy" of the PT. If he's no hero, why do we care about his story at all? The Clone Wars is using the greater amount of screen time to tell a better story - start the guy off as a hero with intelligence and many likable qualities and then just start throwing the kitchen sink at him.
His society is fucked up and corrupt, the war is going badly, the clones are being treated unjustly, he can't be with the woman he loves because of stupid Jedi rules, he's constantly worried about his padawan's safety and is told that he's wrong to feel that way, and he's on a mystical journey that shows him he has greater powers (and responsibilities) than everyone else, and possibly is above all the dark and light side Force users.
And if Anakin is the only person who is right and everyone else is, maybe not wrong, but just not in possession of the whole truth, why not solve all his problems with one sweep of the hand? Isn't that his job, after all?
If they keep going the way they're going, they'll construct a perfectly plausible scenario under which anyone would snap. Anakin can become evil without ever losing the audience's sympathy.
