The only one on that list that I've seen is Napoleon Dynamite, and that's THE worst movie I've ever seen. It was pointless, boring, and just overall stupid.
Napoleon Dynamite sucks balls. Anyone who has ever bought one of those "I heart Pedro" T-shirts should be beaten to death with it. That is, once gunslingingbird and I have pissed on it. Ouch. Wet, smelly and painful. That'll leave one hell of a mark. Lorf.
