"American Horror Story" follows a great tradition of normal, unsuspecting families being thrust into a full-fledged war with the supernatural. The show's creators, Ryan Murphy and Brad Falchuk, best known for bringing smash-hit "Glee" to FOX and (in a darker and more disturbed vein) "Nip/Tuck" to FX, drew inspiration from standout films like Rosemary's Baby and Don't Look Now, but there is an entire sub-genre of haunting we can examine as we prepare for the release of "American Horror Story."
