Last I recalled, there was only 1 fart joke in the whole saga, and Jar-Jar's antics were short lived. Both of these were in TPM. And maybe Anakin wasn't as heroic was we might have depicted, but I do agree that the galaxies greatest villain would have started out as a whiny teenager. As for his turn to the dark side, I felt it was very tragic. He sold his soul the devil and ended up loosing everything, all because he want to save his wife from dying. He starts off being motivated by love and attachment, and evolves into lust for domination.

Annie wasn't merely a whiny teenager. He was DEFINED by his whine. His whine infected his every statement and facial expression. Vader would not have been like that.

Anakin's turn wasn't tragic because he was this unlikable pathetic asshole who just became more that way. If Lucas had kept to the original idea and made him a good guy who turned bad then it would have been tragic.
