Honestly? I think Joss likes making people hate him. He feeds off the rage like some kind of negative karma vampire. The more he pisses us off, the more powerful he becomes. The only way to fight back is to remember that at least we got seven good seasons out of him, and no one can take that away from us. Also, just keep telling yourself it could be worse. He could be crazy and talentless, like Stephenie Meyer.

Moral of the story: just because someone is creatively brilliant doesn't mean they can't also be a complete douche.
