I don't think that horror movies create serial killers, lol. I do believe that you can be influenced by movies. As long as you can see, hear, and feel you can be influenced by anything, otherwise, why do we grit our teeth or have our bungholes clamp shut hard at that pivotal gory part in (insert movie)?

We like to be scared, that's why we watch them. Cheap beer and drugs make serial killers.:cool:
