So I finally saw it, and coming from the point of view of a guy who was a young child when the first trilogy came out (at least the second two) I have to say it was very well done, albeit bittersweet.
I don't really see where everyone gets off knocking on all of the acting, granted the love scenes weren't that good, but they never have been in any of the star wars series, even the first trilogy. I believed that the acting was where it needed to be, not too spectacular, but enough to instill emotions in us, I know I came to tears multiple times due to emotional conflict that came from recognition of what the characters were feeling.
Special effects were well done, the light saber battles did have some bad camera angles, especially the beginning fights, but not once did I speculate between what was computer animated and what was really filmed, which I think is quite an accomplishment. If you think about it, the lightsaber duels seen in this movie were unlike any shown in the first trilogy, there is a much higher level of skill with a light saber with those who fight in these movies as compared to Luke/Darth battles. Because of that, there is a lot more action, so it may be dizzying to some, but that's the way it should be. These saber duels are battles between highly skilled Jedi, whose senses are far beyond those of a normal person, so they will be dizzyingly fast and twirly.
Now to the discussions dealing with story and whatnot.
Why did Yoda and Obi Wan go into hiding even though there were remaining Jedi? Because the whole Republic/Empire had been turned against them by Palpatine. When you become an enemy of the state, you aren't exactly recognized as a hero anymore. Many of the people of the Republic/Empire were in fact more prone to the dark side, and would happily dispatch Yoda had they a chance.
Windu was supposedly the best with a lightsaber according to previous movies, so did he actually have a chance at defeating Palpatine even if Palpatine were going all out (I'm not so sure he wasn't in the first place)? I'd say it would be a close battle, however Palpatine's knowledge of the force might make him the victor anyways.
I felt like my heart was being wrenched free when order 66 came and all of the Jedi were betrayed. I felt like Lucas did a great job of displaying the pain of betrayal in those scenes, poor hottie Jedi.
I also felt a little ripped off when Windu went to arrest Palpatine and he discarded with the accompanying Jedi with ease, as I was looking forward to Palpatine taking on at least 3 Jedi at one time. But if you think about it, they were in an extremely encolsed area, that would make fighting difficult, especially if you were worried about making contact with allies, something Palpatine did not have to worry about.
One thing the movie did make me think about was the philosophies that are dealt with within the force. How easy it was for Anakin to turn to the dark side if, for nothing else, love, something that we look upon as beautiful and good.
Overall I think that this movie was kickass. Definitely up there in quality with the first trilogy, but then again, I love all of the movies, as they all have their place in the overarching story (yes even Episode I has its place).
Oh and the funniest part of the movie - Yoda walking into Palpatine's little office and owning the guards with a flick of his wrist.
