I agree bossk on the bad scripting theory. Throw in the fact that alot of the dialogue was read in front of a bluescreen and you can understand how it can be kind of flat. I have actually grown to like TPM more than AOTC. I think because of the whole cheesy love stuff with Anakin and Padme. Darth Maul was great and I wish he would have been given a chance to develop more as a character before getting chucked down a reactor shaft.
I disagree with ROTJ being inferior to ANH and ESB. Probably because I have such fond memories of being a sophomore in High School, ditching school the day it opened and being first in line in CA. Seeing the line wrap around the block and go as far as the eye can see was something. The duel with Vader ruled and the symbolism with the whole unmasking left a lasting impression on me. (mean old Vader really being just a gentle old man inside) Monsters aren't always what they seem. I actually like the Ewoks. People ask how could these little furry things beat the big bad Empire. Simply put, the Empire was not prepared for fighting of a primitive nature and the Ewoks were fighting for their basic survival. The thing that ruined the Ewoks in my view is the follow up movies and cartoon series. They made them pretty lame but as far as Jedi goes, it worked for me.
