Beware of things that go bump in the night. It is more suspenseful than scary, but weaves the story well for what it is trying to portray. If one does not buy into that, one will be less impressed with the movie. Early on, Dalton, their son goes into the attic, falls, and the next morning is in a coma. Except the doctors cannot understand precisely what or why he is like he is. Meanwhile, the wife sees things that terrifies her, so she wants to move to a different house, thinking the house may be haunted. Unfortunately, matters do not improve. Calling in some paranormal investigators, they state that Dalton is being possessed by demons. At about the half way point of the movie, things really escalate. And a terrific ending, which is obviously why there are sequels. I am not going to give any spoilers. It is quite entertaining for its genre.
