I once saw some kind of film documentary discussing the making of the original Star Wars films. It struck me that Lucas and his wife during the time, Marcia Lucas, were a great team and that Marcia was really the only person who could tell the guy, "No." We just watched all the films in order and it's plain there is a cheesiness in the newer work that was obviously left of the floor in the first set. Not to say Lucas isn't amazing, he is, it's just that it seems he does better with her as his other half in creating the stories, her contribution created an authenticity. Visionaries can veer too far into their own heads and usually benefit from some down to earth criticism. No doubt, it's impossible to tell a guy like George Lucas that a thing doesn't work but his work was better with that influence. I doubt Marcia would have let the writers and film time be devoted to Jar Jar rambling on. I bet if they could rebuild a working relationship the sparks would reignite, much like Elton John and Bernie Taupin...some talent just demands it's other half.
