I liked the movie more than I expected. I figured it would be good, but it exceeded my expectations. The Star Wars crowd did not let down either, the nerd ratio was definitely on the high-end. The story was great. Perhaps my only negative, and it's minor, was that I didn't care much for the idea behind the droid general, although his saber moves were pretty impressive.
So the second arc of the Star Wars saga is concluded. I'm left really hoping that Lucas takes a stab at the final third arc with episodes seven through nine. We'll see!
