is that Revenge of the Sith is not meant to be viewed alone. Starting with The Phantom Menace, Lucas was developing the Anakin character as having attachment issues. Obviously, any young child would hate to leave their home, their world, and their mother, but that is when Anakin's turn starts. It's not something that just happens in Revenge of the Sith.
He turns because he couldn't save his mother during episode 2 and when confronted with the same premonitions about his wife, he can't bear to let her die as well. And having grown up with Palpatine as a close confidant, he's easily manipulated into betraying the Jedi for the sake of Palpatine and the offer of power that he brings. Then of course, once he's started killing the Jedi and everyone else, there's no going back.
I love the contrast of a weird little gnome with a funny voice being in the greatest Jedi Master alive. It's a great dichotomy and a powerful lesson to not judge based on appearance. Plus his inverted speech patterns are awesome. And like Gollum, very fun to imitate.
I would say Luke Skywalker the unlikely farmer who become a Jedi Knight. Mark Hamill was great in this role from the young Jedi apprentice rescuing a princess to the Jedi Knight facing Vader and the Emperor. Han solo by Harrison Ford is a great character too but he does not bear all the burden as Luke does.
