It was way to dark for me. Anakin turns to dark side, Palpatine's face melts, Anakin kills to young padawans, Clones kill all the Jedi, Anakin looses and battle and burns. Padme dies of heart break.
Really, sure, the movie is well made, but the plot just isn't that good to me. Nothing positive about the SW storyline has come from Revenge of the Sith (expect for maybe Luke and Leia being born).

I enjoyed Attack of the Clones more then this one, so that is my opinion.
