Speaking of the prequels it is obvious that Jar jar was meant to have a role in the entire trilogy and when the fan did not like him Lucas reduced him to the bare minimum. Then he put Jango Fett because he thought fan boys would be pleased. That almost worked, but not really. Then he dropped the midichlorians idea because fans did not like it either. I think Lucas should have kept Jar Jar and turn him into an interesting character as the trilogy goes. And he should have kept the midichlorians angle too and turn it into a real plot of the story, instead of being afraid to upset fans. Those to me are real hints that Lucas was not driven by his own "vision" of the saga but pretty much tried to please the audience and failed. Because an audience is pleased when something coherent is told, even based on characters or plots that looks odd. If you can take something that an audience don't like at first and turn it into something worthy for the story, then you earn respect from the audience. That is what I thought when I saw The Phantom Menace for the first time. I was not really THAT letdown because I trusted Lucas to go somewhere with those strange charcacters and subplots. But no. He had no real vision.
