Firstly, like TheBoost said (and part of what I came here to post, dammit) is Edutopia. God knows we need all the help with education we can get.
Personally, I love the man. George Lucas is something of a hero to me, or at least a person I greatly admire. The Star Wars movies, and especially the OT, have really helped define who I am as a person; from what I want to do when I grow up, to what I'm doing in school, to my attire (I mean Star Wars shirts, not flannel).
He seems like a normal guy with a good head on his shoulders. He seems to have a good idea of what his shortcomings are. He seems to have a sense of humour. He definitely has vision and some great ideas.
I don't hate him for the "mistakes" (from my point of view) that he's made with Star Wars. I'm angry at him, sure, but I'm angry at him like a friend of a guy who asked out a girl you were into. Sure it sucks, but it ain't the end of the world. I'm not going to end the friendship over something like that.
I feel kinda bad that he's being held back like he is. I feel like, with a better team of support, unlike all the useless ass-kissers around him now, he could actually crank out some more amazing films.
Either way, I think he's a pretty swell fellah.
