content: A Family of Four (Karen Black, Oliver Reed, Two-Time Oscar-Winner:Bette Davis and Lee Montgomery) rents a House for the Summer and they are Beforehand Overtaken by an Unseen Compulsion.Directed by Dan Curtis (Trilogy of Terror 1 & 2) made a Good Ghost Film but the Movie is Familiar and Predicable. Based on a Novel by William F. Nolan (Logan`s Run), he also Written the Screenplay with Dan Curtis and Robert Marasco. The Cast is Good, Bette Davis hams it a bit too much than the Cast. The Film is Slowpacing and Downbeat Atmosphere. The Movie does have some Genuine Moments. Karen Black does have give the Movie, Best Performance. Although for all it`s flaws, this is a Good Looking Supernatural Thriller. Grade:B+.
