I agree that the movie went too quickly, and kind of breezed over what should of been some of the most important parts of the move, (Anakin's Transformation.) I also have to be honest, after seeing the first three movies, Darth Vader seems a bit less menacing. In the originals, especially before he saves Luke, Vader actually felt and seemed like a really bad scary guy. However, now having seen him as a cute little boy, and then a teenager/young man, he seems a lot less scary. Especially at the end when he rises, because in my mind I know that under that black suit that has so long seemed to be such a symbol of evil and terror, I know that there is just a young guy.
But anyway good stuff, gotta love the visuals. Beautiful light saber battles, but there were still some noticable flaws with the graphics during certain fight scenes. But otherwise very pretty to look at.
