What's the scariest movie you've ever watched?

Recently I though The Strangers was really quite scary. It's incredibly tense pretty much the whole way through.

I would have to say that I prefer a horror that plays with your mind. So that being said I would have to say "IT". It plays with your mind on so many levels. Clowns just are not the same after that movie......LOL.

Exorcist, The exorcism of emily rose.. That's the best!! I really like those movies.. :)

I have never been a big fan of scary movies because I do not like movies that give me the creeps and cause me to have nightmares for weeks on end,and I usually try to avoid scary movies,unlike most of my friends who love scary movies,one of my friends tried to get me to watch The Texas Chainsaw Massacre a couple years back and I refused to watch it because I knew it would be scary,and I guess that the scariest movie that I remember watching would be Jaws because I am afraid of sharks and that movie gave me nightmares for a long while.
