Anakin's turn is understandable IF you keep in my mind that Anakin really respects Palpatine, as a leader and a father figure, and is SO desperate to keep Amidala from dying like his mother, he won't ask a lot of questions. I just wish II had made a bigger deal out of Anakin's search for his mother, and Anakin's weird desire for a dictatorship. As it stands, those things actually amounted to very little screen time. I had friends who barely remembered Anakin's mother death 3 years later, and they REALLY didn't remember Anakin's comment about dictatorship and that lone scene beteween Palp and Anakin. It was up to II, not III to lay that foundation. I actually really like Episode III, come to think of it.
