"The problem with movies and books is they make evil look glamorous, exciting, when it's no such thing. It's boring and it's depressing and it's stupid.

They're shallow, empty, boring people who couldn't give you five minutes of interesting conversation. Maybe some can be monkey-clever, some of the time, but they aren't hardly ever smart."
