@Mushroom, I've always actually liked the redemption of Darth Vader. I thought the closing of RotJ was probably the best part of that movie (with the Battle for Endor and those damned Ewoks being the worst).
Clones gets the prize for worst Star Wars movie. I've mostly blocked it out apart from some god-awful dialogue about sand. Only good romantic dialogue ever in Star Wars was ad-libbed by Harrison Ford.
