--A lot of screaming.
--A lot of explorations done in the dark, when everyone should be sleeping.
--The presence of a ghost that must be pieced together like a jigsaw puzzle, night by night.
--A secret room containing a skeleton.
--An old crime that must be researched on-line and in the library.
--A ghost that can manipulate electrical power and lock doors.
--A ghost that materializes primarily in bathrooms, and is reflected in the lavatory mirror.
--An ending that suggests that the ghost is still inside the house, and that the evil will continue, a la Amityville and Carrie.
