I also have to go with McCallum. For all of Lucas's problems and subborness as far as the prequels go, and his constant changes, at least Lucas has reasons, even if most disagree with him. McCallum is only a drone who doesn't seem to be able to think for himself, only say why Lucas is great. I might have more respect for him if he would come up with something that wasn't along the lines of "Lucas is a genius".
