And the only good part of ROTS is the Order 66 sequence.
I respectfully disagree. I didn't know any of those characters slain in that montage. We have this abstract idea of what Jedi are supposed to be and what they are supposed to do, but we never go to know any of these characters. Of course the ascent of evil is a tragedy, but it's not a personal one in the case of ROTS.
The more I think about it, I think ROTS is the worst of the PT films.
