Sometimes a mystery can be what makes a movie. Sometimes, it feels like flagrant laziness. _The Open House_ is the latter. The acting is fine, and the characters constantly and blatantly saying things like "Isn't it crazy how there could be a person hiding in your house right now?" might get in your head some, but _The Open House_ is a far cry from any sort of actual success. _Final rating:★★ - Had some things that appeal to me, but a poor finished product._
