Some brief thoughts about "Revenge of the Sith," with spoilers, so quit reading if you haven't seen it yet and don't want to know about specifics.

• The opening was the most visually stunning battle scene of the entire series. Much the way the Seinfeld finale brought back every bit character they could possibly think of in an attempt to go out big, Lucas clearly threw everything he had at the screen, and it worked. Just as the extended battle at the end of "Return of the Jedi" capped an increasingly visually adventurous trilogy, this scene embodies what the prequel trilogy was meant to accomplish in storytelling terms.
• The reaction of right-wing nutcases to the political element of the story is predictable but stupid. A story about a democratic republic falling to evil is necessarily political, and if you don't like what you think it reflects, maybe you ought to be thinking about what it is you do like. Anakin saying, "If you're not with me, you're my enemy," is probably the only thing that could be reasonably connected with the current political atmosphere, but the composition of the line follows logically from his earlier statement that he hopes Obi-Wan is still "loyal to the Chancellor." (Mace Windu's declaration that, "[Palpatine] controls the Senate and the courts, he's too dangerous to live," is an amusing coincidence, but was written well before the current battle over the courts began.)
• The tranformation of Darth Vader from a man to an obsidian cyborg has some interesting ramifications for the original trilogy. As far as I can tell, Obi-Wan left Vader for dead. This may help make sense of the confused continuity which starts with Obi-Wan telling Luke his father was killed by Vader, then admitting that Anakin becoming Vader was similar to his being killed, "from a certain point of view." Obi-Wan returned to Naboo thinking Vader was dead; when Vader returned, "more machine... than man," it would've been easier to rationalize the whole thing. He's already soaking in self-loathing for having failed Anakin as a mentor; why add on to that by realizing he could've -- should've -- killed the guy 20 years before?
• Speaking of Naboo, isn't that kind of a dumb place to take Padme and her gestating offspring, since it's also Palpatine's home planet and you've got to think he has some kind of intelligence apparatus there? I mean, obviously it worked out, since nobody ever discovered Luke and Leia, but still.
• The relative lack of passion of Vader in the original series is an amazing contrast to the one scene featuring cyborg Vader in "Revenge of the Sith," with James Earl Jones mimicking Hayden Christenson's cadence perfectly, showing only concern and anguish for Padme. The overhead shot of Vader crying "Nooooo!" may be the dumbest single moment in the entire series, but the scene as a whole informs the original trilogy like few other prequel moments.
• The hand-to-hand fighting abilities of the Jedi seem out of whack to me. They're all awesome swordfighters, even though, presumably, they've had no swordfighting enemies to deal with lately. The Sith are only recently returned, and the other bad guys don't use lightsabers. On the other hand, you'd think they'd get a lot of practice at using their little Force-guided telekinetic moves, which they are actually really sloppy at employing. A quick Force-shove would go long way in a fight against a half-droid/half-meat bad guy with four arms and a lightsaber in each, I would think.
• It was dropped in so subtly you could've coughed at just the right time and missed it, but apparently Palpatine (or his Sith mentor) was responsible for Anakin's virgin birth.
• Yoda riding Chewbacca. Like I said in the last post, everything you could've expected it to be.
