49/100 Basically, a "Grave Encounters" clone with a pinch of "Blair Witch" mythos about a paranormal research group investigating an old, deserted sanatorium. Found footage format which is just like watching an episode of "Ghost Hunters", except the ghosts bite back in a big way. Well made with some good scares and a lot of 'out-of-the-corner-of-your-eye' stuff but nothing really new to add to the genre. -- DrNostromo.com
