This is an unknown gem of a movie that has some real chills. Like much of it's genre it shows too much at the end and falls apart while fumbling for an (unsatisfying) explanation of the events. Overall, definitely recommended over the "Scream" rip-offs or "Exorcist" rip-offs of the late 70s and early 80s. If it were released today it would probably be a modest box office success.
