I saw the movie on Saturday at the Cinerama in downtown Seattle. (It did in fact remind me of the Uptown in Washington, DC -- it had the same large, curved screen and incredible sound system that the Uptown has, though the Uptown is larger and holds more people. But if you want a great movie experience in Seattle, the Cinerama is the place to go.)
I thought the movie itself was great. Definitely better than the first two, and an excellent way to wrap up the trilogy. Of course, the effects were better than anything I've seen lately, and the lightsaber battles (all five of them) were beyond anything in Star Wars films before. The fight between Anakin and Obi-Wan was especially tense and thrilling. I suppose if you're not planning to make any more Star Wars movies, you'd better make your last battle the best one. Maybe the best parts were the ones I was expecting: the beginnings of Darth Vader's career, how the droids end up where they do, and what all that blather about the midichlorians and disappearing ghostly Jedi really meant.
Some of the dialogue was cheesy and wooden, and the two little girls sitting next to me giggled at every bad line. Also, it ran a bit long for a Star Wars movie, I guess because George Lucas needed to get every last item into the story. But I really enjoyed it, and I can't wait to see it again when I get back to New York.
