The Descent was great - although I'm not sure why the director went for gore. It was scary enough without it. The same director made a film called Dog Soldiers which is supposed to be pretty good. I highly recommend The Ring. Not a lot of gore but really creepy. I'm sure the Japanese version is pretty good too (The Ring Virus) I saw a movie in high school called I, Madman which at the time I thought was really good. But then again, I thought Halloween IV was really good back then too. For creep factor alone, I love The Shining. Carrie is also really good.
