I couldn't agree more about King of the Hill. The animation is unnecessary, intentionally simple and boring, and the show isn't even very funny. I definitely get discouraged about American animation when I think about that show, but then I think about the good ones and it's OK again

Actually, I was paying it a compliment, at least as far as trying to expand the audience. The Simpsons is almost as adult-oriented, but it reads more like a parody of children's animation, as do most other adult-oriented cartoons. But KotH is a straight-up sitcom. I think that's important, and it's as important that it's successful.

I happen to think it's pretty funny, too.
