X-Men 3... I wanted Magneto to win. Superman Returns... I wanted Lex Luthor to win. I WANTED SAURON TO WIN.
But no, the pures always win in the end due to some magical chain of events made awesome with movie magic.
Bad good guys are better than good good guys and I don't mind when they win. The chick in Kill Bill comes to mind.
Good good guys suck.
Edit: Am I an evil dictator at heart?
