Kasdan on the other hand challenges Lucas all the time

Well these conversations prove that the notion that prequels failed because no one challenged Lucas is wrong. It is pretty clear to me now that he always had it his way. Luckily in OT he had relatively great ideas as opposed to the prequels.

Except he didn't always get his way on Empire. Which might be why he sought out someone like Marquand for the next film. And notice Gary Kurtz didn't stick around for Jedi.
