Yeah I loved it. Hayden managed to act a little bit this time around - the scene just after Obi Wan has cut off Anakin's legs was crazy, both Ewan and Hayden were excellent in it.
Only gripes:
1. No Han Solo

2. Vader's AWFUL "NOOOOOOOOOOO" after the death of Padme, and
3. Yoda's random mentioning of Qui Gon to Obi Wan, with NO RESOLUTION WHATSOEVER. What was the point, really.
Other than that, the movie was insane. I went to the midnight screening, people were cheering at the start and end, it was excellent. Didn't know R2 was so versatile.
