I agree with the other person that it is one of my favorites as it's one of the only movies to ever actually creep me out (though not a fan of the ending) as I feel horror should.

My wife is a big horror fan, and I can say that a majority of the ones I've seen with her are extremely predictable and rely on cheap tricks like jump scares most of the time, so outside of campy horror stuff or classics that I grew up with, it just doesn't do anything for me.
