I would have to say the Grudges scared the living crap out of me girlfriend, but good thing i was there for her to snuggle into. But i would have to say the Hills have eyes, only when they turn a corner and the monsters end up killing them
I never really get scared of movies but I get freaked out,one of the only movies that scared was Halloween the uncut editon cos in the old one it was to scary to put in!!!!*brrr*Shiver*
Most horror movies I've seen haven't scared me, but rather make me juat those certain moments, but having to pick one I'd go with House on Haunted Hill (1999 version)
