The Pedofile
When we're first introduced to him, when he's just about to kill the young boy, did anyone actually take note of what he looked like? Like his makeup and the music, the atmosphere.
I watch heaps and heaps of horror films and I have never been all that scared until that one scene. I literally had nightmares and cannot watch that scene again.
It might just be that I'm a 16 year old girl, but heck, that scarred me.
