I belive it's kinda pointless to argue about what film is better, not because it's impossible to tell, but because opinions are just like watches and clocks. Everyone has its own, and we all belive our own watch is correct, but none are, some are a littlbe bit early, others a little bit late.
Ah, but Revenge of the Jedi (I prefer the "original" title) is better than AOTC. My watch, I mean, my opinion.
