I have something in all 3 I liked.
TPM: Ray Park was bomb ass with his skills as well as the overall plot and starting point for Anakin Skywalker. Liam Nesson also was great. Still a bit more craftsmanship in this one than the other 2.
AOTC: Fair. Least we learn of Fett's roots as well as the stormtroopers' predecessors. And the beginnings of Darth Vader showing. Christopher Lee was excellent for his role. A little more exposure to the SW universe as well.
ROTS: packed with urgency and intensity. Has more duels than any others. Wish they would have filmed an alternate ending like in the ROTS game for PS2. For a brief time, Anakin shone himself a true hero of the galaxy.
That's right, Bixby Snyder folks.
