The purpose of this sort of film is to set goose bumps along your arms and make you jump and to that end the director has done a damned good job. My wife and I jumped several times during the movie even though we knew something was about to happen and numerous times I had chills running down my arms. This is of course all down to the effective use of music and sound effects together with the images, without them you probably wouldn't react because there is nothing here that you haven't seen before. It is just very well combined and presented.
The story is the classic haunted house tale of a new family being tormented by an evil entity and the good guys that come to the rescue and is allegedly based on a true story. I noticed that some reviewers have referred to an interview with one of the daughters of the family but to counterbalance that the current owners of the house say it is all baloney and nothing has or does happen there. But there again they would say that wouldn't they?
This is a great movie to give yourself and some friends a thrill at Halloween and there is no blood and gore which is a plus but don't watch it on your own if you are of a nervous disposition.
