Saw it, loved it, excellent movie. It was an ideal way to end the series, connect the trilogies, and tie up a great many loose ends. And it was so perfectly tragic.
If I may be permitted to pick a few nits:
(There were very few things I disliked about this movie, but, being a fanboy, I am compelled to discuss them)
Chewbacca showing up was lame. He didn't do anything, and it added nothing to the character except for some unwieldy baggage about how Chewie used to be a war hero. There is nothing in his character in Eps 4-6 to suggest that he has ever fought nobly as the second-in-command of a wookie army, or that he has any experience with the jedi at all, let alone Yoda. Chewbacca is, at best, a beloved sidekick who has never had anything approaching a character arc. Now he has one, and it doesn't go anywhere, and it's stupid. It might have worked if he had been in the background as a young wookie mechanic, but as a leader in the army he was out of place. Fan service is one thing, but changing the entire nature of a character is going too far.
Padme dies? But Leia remembers her mother, and how sad she was! Everyone has always thought she was talking about Padme--are we to believe that Luke was earnestly questioning her about her adoptive mother? Why did he care? If Leia is not talking about Padme, the entire point and impact of that scene is undermined and destroyed. Lame-o to the max.
If either Anakin or Obi-Wan had remembered that they knew how to shove people with the force, that lava fight would have been a heck of a lot shorter. It's like Superman on the Superfriends--you can shoot lasers out of your eyes, you moron! Do it! I suppose Obi-Wan's reluctance to force-shove could be attributed to his lack of will to actually kill Anakin (which was a very cool plot point, by the way, and a remarkbly strong character attribute that resonates throughout the 6 movies). So I can excuse that one.
Now, if I may be allowed to speculate:
The business at the end with Yoda telling Obi-Wan that he could learn how to live forever was very interesting, and a nice explanation of how the two of them are able to disapparate when they die instead of just falling down like all the other jedi. The inclusion of Qui-Gon in that discussion, however, was the real kicker--why bring him back in? Was there something about his death that I missed in the first movie? Are they planning to do something with him in the future: say, in one of the TV series? Palpatine's declaration that "only one person has learned how to conquer death" seems, in hindsight, like yet another reference to Qui-Gon. Intriguing.
