By far the scarriest movie I've ever seen. If this ever happened to me, I'd be ruined for life most likely.

^ Very good movie.
As far as movies that scare or give me a shiver, Stephen King's Misery is probably near the top of the list. That nurse gives be a shiver just thinking about it. Children of the Corn was pretty scarry, and It. I have never liked clowns, and It made it worse. Still love Stephen King though!!! Pet Cemetary was a pretty decent flick too!!
