“An Amityville Poltergeist” (*1/2 out of four) was a leaden horror show about a young brat (Parris Bates) who takes a housesitting job from a deranged old woman (Rebecca Kimble) and then soon finds that the house is haunted by all sorts of loud shock effects and paranormal activity and he has to try to keep his sanity and get out alive. Yet another film that cashes in on the “Amityville” name without adding anything to it; in fact this was originally titled “No Sleep” in production but had its title changed by some clever producer at the controls. Film, unfortunately, has no cleverness of its own and is slapdash and weak. For die-hard “Amityville” completists and horror geeks only.
