5. THE SHINING. Kubrick's clinical precision gives an already frightening Stephen King story an ice-cold edge that cuts the viewer to the bone.
4. THE VANISHING. Maybe the most chilling ending of any film because the abducted turns out to be...you, the viewer.
3. THE TEXAS CHAINSAW MASSACRE. The question "What can stop a madman?" gets a terrifying answer: nothing, if he is determined to kill you.
2. THE BLAIR WITCH PROJECT. Simple, yet terrifying in its perfection, particularly when the hunted turn on each other.
1. HALLOWEEN. Most horror movie protagonists don't come with a backstory. They're too complex, and needlessly complicate the simple formula of terror. That is, unless that protagonist is Michael Myers, and the story is Halloween.
BONUS: THE EXORCIST. It comes on at 3:30 p.m. on CBS this Saturday.
