Well, the original poster captures my thoughts nicely - if anything, I may have been a bit quicker to see Lucas' true colours.
There are still millions of fanboys who worship the ground he walks on but more and more fans are seeing the truth.
One fluke in 1977 and then a steady decline. If you see him in interviews he really doesn't know much about the story or the characters - contradicting himself or relying on rationalisation squads.
Yoda, for example. We all knew who Yoda was. We knew the character. Kershner knew the character. Lucas didn't. In Lucas' head, Yoda is a CG frog with a lightsabre, always up for a fight and who talks in ridiculous sentences. He is dumb, violent and has relations with wookies.
Lucas really doesn't have a clue.
