I do feel bad for Lucas for the flack he gets from the prequels. Look, I hate the prequels as much as anyone, but Lucas just made some bad movies and people act like he purposefully messed them up just to make them angry. He was experimenting. He was trying to make good movies based on ideas he was passionate about.
The problem wasn’t that he made bad movies. The problem was that he infringed upon the movies we already knew and loved. The prequels introduced midichlorians and ruined The Force. They ruined Yoda. They took Anakin and turned him from a noble man seduced by the darkside, into a whiny teenager seduced by the darkside. Then he disappeared the OOT and ruined the films with his idiotic SE changes.
If he had just made bad prequels, he would still be looked upon in a very favorable light.
