I didn't realize ROTS had such a bad reputation. I thought it was clearly felt by fans to be the best film of the prequel trilogy. But, I can be out of touch with these things. For me personally, ROTS is actually in my top 3 Star Wars films. It's one of the very few that actually provoke an emotional reaction in me. For as much flak as the actors get for the prequels, I thought that Hayden Christensen, Natalie Portman, and Ewan McGregor did a really excellent job in the last few scenes of the film. I can really feel the heartbreak from Portman, feel the anger seething out of Christensen, and feel the utter disappointment from McGregor.
