Plus Tim Burton, as much as I love him, would probably do something to spit all over the Star Wars characters and universe, kind of like Batman (I like the movies, but the portrayals of the characters are horrible. I really don't think he understood them that well).

Although I mostly enjoyed the prequel movies, I agree they left a lot to be desired. I can't blame the bad acting on anything other than poor dialogue and directing on Lucas' part though. No member of the cast in these movies should be putting in performances as bad as we saw unless the material itself is bad (which it was). I have to give Ewan Mcgregor credit for doing as good a job as he did with what he had though. Hopefully if anything else happens in the Star Wars universe Lucas will have the sense to let someone else direct and write it. I have no problem with him handeling the overall story since the series is his baby, and he can actually handle that. His dialogue and directing however lead me to believe he's never actually interacted socially with another human being. Ever.
