SW:III was undoubtedly an improvement over SW:I and SW:II in all aspects. But considering how those two had all the character depth and plot complexity of kid-flicks like Goonies or Honey I Shrunk the Kids, I'm not exactly praising the movie to the high heavens. Without giving away too much of the plot, I'd like to list my impressions after the movie.
1. Anakin is not a tragic antihero who is caught in an epic struggle between the lust for power and his searing conscience. No, he just wants his mommy, and a wife who can love him like his mommy... and hey, why not throw in a galactic empire in there just for kicks. He even balks at the thought of children because it would expose himself to a world beyond his tight circle of love with his wife/mom.
2. Yoda purposefully uses Korean/Japanese grammatical syntax just to tell the audience that he's Yoda, not as a natural outflow because he learned English as a second language.
3. Lucas must have really loved the RotJ speeder chase on Endor. Every action scene moves with the same frenzied pace. Why make your ILM guys render scenes with detail to the nth degree if you're always going to be showing it whiz by at ludicrous speed?
4. In RotJ the emperor's most dangerous weapon was his strategy, not his lightning bolts or his saber skills. We saw Luke almost losing it completely because he was confronted with the awesome foresight of the emperor, realizing how he had countered the Rebels' every move. Sidious is supposed to have concocted everything from start to finish in SW:I,II,III, but he's never really given any credit for it. He never gets his "everything is according to my plan" speech. You never see how exactly the Trade Federation, Dooku, or any other villain was ultimately duped by Sidious, how the Jedi were influenced or clouded in their judgment, how ANYTHING of this really transpired. We're just forced to infer everything because, well, he's emperor and got his sidekick didn't he? Btw, who wanted to see the emperor fight? Didn't we all want to see Vader kicking some Jedi arse??? Also, you'll see Yoda doing some morally questionable telekinetics as he uses the Force to ATTACK.
5. We see some of the technology from SW:IV,V,VI in SW:III. And it's jarringly cheesy-looking compared to the fluid Naboo models and everything else that is supposed to be antiquated compared to the bleeding-edge tech of SW:IV,V,VI. The prequels should have had cruder ships and simpler tech so that there would be signs of technological progression, not regression.
6. You will never look at Vader in the same way (and not in a good way). I almost wish I'd never seen the prequels. Lucas really messed this one up, guys.
