I think that religion stops people from thinking. I think it justifies crazies. I think flying planes into a building was a faith-based initiative. I think religion is a neurological disorder. If you look at it logically, it's something that was drilled into your head when you were a small child. It certainly was drilled into mine at that age. And you really can't be responsible when you are a kid for what adults put into your head.
Last thing you want to do with a good movie is hold the audience hostage. As an entertainer myself, I just know it's better when you leave 'em wanting more than to stick around too long.
