Horror movies set in storage locations
This is a new angle in the horror movie genre akin to claustrophobic settings in trains and airplanes. I think it's a great idea. Usually the storage facility is large, multi-level, and usually run-down.
There was a direct-to-rental-video movie two years ago that was set in a dilapidated storage unit run by a sleaze ball. But I can't remember the name of the movie.
This movie relied upon the faulty lighting fear prop commonly used by Hollywood. This is when there is little, none, or faulty light illumination. Also, in the movie, at the beginning the two women investigate a lower level storage locker without a flashlight. One of them relies upon a lighter.
