Well, to start off, it's often inspired by a great author of the past, (i.e. Edgar Alan Poe, Mary Shelley), so you can always be assured that the storyline is there.

Next, horror films start playing with your mind and thoughts, overlapping the fantasy, the supernatural and the real world, blending it all into one.  That alone can give you a new sensation and feeling other films can't evoke.
