the movie does show the house is haunted. when danny gets attacked by the woman in the room and at the very end of the movie when shelly duvall is running around the house and shes all of those people and the skeletons in the lounge area. although i do admit it took me a while before reading the book to realize that they all werent having mental breakdowns. the movie definitely could have been a little clearer there
