It's also a matter that even actors find playing the villain more fun than the hero. Heroes tend to be cut from the same cloth, especially in film. The nice guy, the good guy - Superman is a good example. It's only in the past, what, twenty years or so that the antihero and the grittier heroic types came to the fore? I don't know the specifics.
Meanwhile, villains can come from all walks. You can have your crazies, your power hungries, your "the world is diseased" types, so on and so forth. My personal favorite type of villain is the one that... you can kinda agree with. You don't approve at all with what they're doing, but you can totally see their reasoning for doing it.
Second is probably the one written so well that you find yourself hating them without even knowing it.
