The Disappointments Room has all the ingredients of a good horror film, which is perhaps part of the problem. The film seems content to fill in the colors of lines that have already been well drawn. It has no imagination, adds nothing new, and simply plods through the motions.
Married couple Dana (Kate Beckinsale) and David (Mel Raido), along with their young son Lucas (Duncan Joiner), move to an isolated old house in the country. Not surprisingly, we soon discover two things: 1. Dana and David have recently experienced a traumatic event, and Dana is not dealing with it very well; 2. The house they are moving to has its own traumatic past, one that soon makes its uncanny appearance to the more vulnerable Dana. She starts seeing things and soon the line between hallucination (or supernatural occurrence) and reality starts wavering.
