ROTS had the worst action, the worst acting, the worst directing and the worst editing of all three. I don't know what you're on about.
TPM looked like a film, was way better paced, edited, written and acted. Also, the duel at the end was superior, by far, to any in Revenge of the Sith. All of the action in ROTS was distinguished mentally-challenged, and again, looked like video captured from Star Wars: Battlefront
