It was good, but not the best.
My Observations:
1)I was disapointed in the opening space battle I was hoping for something mor like ROTJ, the battle only follows Anakin and Obi through space, I was hoping for the cutaway between the interior fight (and travel) and the outside battle between the starships and the fighters. I wanted to see V-Wings attacking Seperatist fighters and ARCs leading torpedo runs on enemy frigates and cruisers, that sort of thing.
2) I thought a bunch of the scenes between Anakin and Padme' were redundant
3) The Battle of Kashyyk was too short, it seemed that it either should have been cut to just the scene with Yoda or been longer and slightly more developed, seemed it was just put in there
4) I would have liked to have scene a bit more clone action on Utapau
5) The killing of the jedi could have been a bit longer
6) I wanted to see more of the Venerator!
7) When Darth Vader was created was great right up to the point where he rips of the cuffs holding him down, I would have had him use the force to take off the cuffs and then instead of the scream and beating his chest had him simply look at the ground with his shoulders slumped as if he was defeated and had succumbed completley to the dark side, then on the Star Destroyer give him a powerful stance as he oversees the Deathstars Construction.
8)I thought Samuel L. Jackson's acting was terrible when he died
Were those Imperial Officers clones?
I'll admit 4,5,and 6 are all just things I would have liked to seen but I think the others have real merit, maybe some more footage in the special additions or DVD release.
