Or disturbed you?
I suppose its not all THAT scary or creepy but It (the steven spielburg book also) gave me the creeps and I had nightmares for weeks after watching it. I have a fear of clowns and watching that film made it ten times worse, I couldn't even go past drains or anything after seeing it I was so freaked out by the film, and that whole peodophile notion to it, just ugh....
Hmm another film that I found a little bit disturbing was a japanese film called "freezer", this woman is gang raped by some men, so she kills them and keeps them in those giant freezers in her room and talks to them like they are still alive n stuff, and in the end she throws herself of a balcony.
Schindlers List also disturbed me and greatly upset me too the point I had to stop watching it half way through to cry n then watch it again because it was that horrifying. Its not like those other films were you can turn it off and thank god that it won't happen or whatever because it DID happen and thats in itself is disturbing.
