I believe Lucas is now the unfortunate result of what happens with age. He's gone from being a dynamic, shit kicker off a director to a mellow old man, obessed with his own legacy.

But yes I tend to agree that while Lucas can take credit for coming up with the ideas for all SW films, he accepts too much credit and too much ownership for my liking. I've always thought Lucas was a brilliant ideas man, but hopeless at implementing them. The partnership he had with Speilberg is the perfect example of what could have been with the prequels, ie Lucas behind the ideas and Speilberg behind the camera.
