Your fave scary movies?

With Halloween around the corner, I was wondering what horror films you all enjoy watching. I've always been a fan of horror flicks, from the shlocky to the slick to the ambitious. There's a craft to making someone scared, very different from making someone laugh or well up with tears. I respect filmmakers who focus on horror and try to instill such a powerful emotion in us, something so rarely done with any other art. I guess I'll start with my top 5, in no particular order: Halloween Hellraiser Pet Sematary Evil Dead (although it's often more humourous than scary) Drag Me To Hell Your turn!
