I often tell people monster movies don’t scare me. It’s the real stuff that freaks me out. For instance, I think the scariest horror film is A Beautiful Mind. And I don’t say that in jest. The idea of seeing people that aren’t there is a real fear of mine and the fact that it’s a real condition makes it all the more terrifying.
That’s not to say ghost stories and the like don’t get my heart racing or aren’t a little freaky, but for some reason, it’s the real stuff that gets me the most.
