I’m not going to pretend “Dark House” is an original horror outing. As a film it’s basically a pastiche of “The Haunting,” “House on Haunted Hill,” and “Thirteen Ghosts” with a skosh of “Haute Tension” for good measure. But in spite of the inherent derivations, I couldn’t help but have a damn good time sitting through “Dark House.” It’s deep down a very light on logic party horror film that you can sit through with friends and never be bored with. Even when it’s attempting to exposit the characters back stories, it really is at warp speed so that it can get to the bloodshed and gore. Thankfully I didn’t have much of a problem with that.
