I dunno. I think he's a creative genius AND I think that the OT was the product of collaboration.
As I've said before, I think George is an "idea man." Out of 10 ideas:
- 5 will be abject crap.
- 3 will be pretty good and, with some massaging, can be phenomenal.
- 2 will be pure unadulterated genius.
The OT had very little of the first five, and far more of the latter half there. The PT was the whole range. The trouble is, when you get those 5 awful ideas, they obscure the rest.
I mean, the PT DOES have some cool aspects to it. The lightsabre duels were awesome. I think the notion of making the PT a bit more "political" could have been a lot better if it had been better developed. The fall of a good man to evil is a compelling story. And the action sequences in general were fairly cool. But so much of it just gets blotted out by wacky production design, stilted dialogue, awful "political intrigue," and Jar Jar.
Basically, when Lucas is on, he's almost impossible to beat. But when he's off...boy is he ever off. And nowadays, I think he's off a LOT of the time, and in some pretty high-profile ways.
I also think he's stubborn and doesn't want to take any crap from you, even as he's also genuinely disappointed that you don't dig his stuff as much as he does and thinks it's unfair that you call him names just because he messed with your favorite movies.
So, in a weird way, I think he has, at once, a thin skin and a thick skin. Thin in terms of initially being irked at the insults and criticisms, but thick enough that he says "Well, too f'n bad. They're MY movies, so y'all can just go jump in a lake."
