The story goes, as it must, through the grinder of utterly dependable formula: a terrible and inexplicable event occurs to people, and years later the footage of the victims winds up in the hands of mystified onlookers. This is the initial pitch made by “Hell House, LLC,” yet another entry into the “found footage” division of horror films, where the accounts of would-be victims are well-documented by the cameras they hold. This time, the prey has abandoned notions of searching for vengeful witches or spiritual hauntings and have come to, basically, document something less ominous – that is, putting together a local Halloween attraction in Abaddon, New York. Unbeknownst to them, alas, the abandoned hotel that comes to be the site of their frightful venture is more than just dark rooms filled with strange noises and creaking floorboards. It seems to permeate some sort of threatening energy. Sometimes, the viewing lens will even spy this possibility – shadows in corners, symbols etched on the basement walls, figures moving through doorways, and Halloween props that move entirely on their own. Did they bring some sore of malevolence in there with them, or was it always there, lying dormant? Some wisely suggest leaving behind the project, but one stubborn proprietor refuses, leading to a chaotic and frightening opening night in which 15 people pay with their lives, including most of the original managers.
