This page has gone way off topic in the last few posts. Back to topic...
Since I posted the OP 2 years ago the critical consensus on the 6 current SW films hasn't changed much (According to Rotten Tomatoes) but it has changed...
Star Wars 93% (-1)
The Empire Strikes Back 96% (-1)
Return of the Jedi 78% (-1)
Star Wars Episode I: The Phantom Menace 57% (=)
Star Wars Episode II: Attack of the Clones 67% (=)
Star Wars Episode III: Revenge of the Sith 80% (=)
So people still feel exactly the same about the prequels, they like the original-trilogy a bit less (Surprising given the recent OT love expressed in the lead up to TFA) and they still think ROTS is better than ROTJ but now they prefer ROTS even more!
Madness I say! I still can't really understand why many are so dissatisfied with ROTJ, that they'd actually start thinking it was worse than the prequels.
