What's funny is that the ultimate proof that the flaws of the prequels are directly Lucas' fault is the fact that The Clone Wars, which he has limited involvement with, is VASTLY superior to anything in those movies. In deed, the one part of TCW that Lucas was deeply involved with was the one part that was universally panned, the theatrical film/pilot.
But seriously, had Anakin been depcited in the films the way he is shown on TCW, those movies would have been infinitely more watchable. In some ways, they are not even the same character because Anakin in The Clone Wars is a likable if flawed and conflicted person...i.e someone you want to watch. There is no way that the PT Anakin ever had someone like Asoka in his life.
