But still, let's face it, George is much better as a story man, an idea man, but others should execute it. There's no one around who would say that the actual stories (not the dialogue, but the ideas, the concepts) belong chiefly to anybody but George Lucas. Many other people have designed spaceships and creatures and then created them, but the concepts, for the most part, belong chiefly to him.

That being said, if he is the one to execute his ideas, experience is shown that he works better under pressure. That is, his products end up being better when he has to work his ass off to get it. As was said in Empire of Dreams, the making of Star Wars was hell. His cast and crew balked, a lot of his ideas took forever to turn into reality, the studios were threatening to shut him down, and Lucas ended up getting severe health problems. I'm not saying that health problems are good, but he was forced to think creatively to solve his problems as there were many, and Star Wars is now a classic. With the prequels, he has everything he wants right there in his lap and can do anything he wants with the snap of his fingers. Just film it on blue screen and fix it in post. It's the solution to every problem. See the difference?
