I would take away some of the poorly written dialogue between Anakin and Padme, specifically during Episodes II and III. I would slightly alter the fight between Mace and Sidious (if seen it a bunch and read posts regarding whether or not Sidious let it all happen) because I'm still a it confused. And I would add about 15 minutes to Revenge of The Sith. I love ROTS, but I feel as though the ending was rushed. I know the run time was well over 2 hours, but I think another 10-15 minutes could have helped the pace at the end of the film.
