“Amityville Island” (* out of four) was a numbingly awful horror show about the survivor of killings at the legendary Amityville house (Jamie Morgan) who brings evil to a small and isolated island where a series of experiments are being conducted on both humans and animals in a women’s prison. No relation to the “Amityville Horror” movies but title relates to the Amity Island which was the setpiece for the original “Jaws” but that’s about as clever as this dispiriting trash gets. Film mauls you with so much bad acting and visual effects you may feel more assaulted and shellshocked than some of the victims. Shark scenes in particular are so cheap and amateurish they really have to be seen to be believed but by no means is that anything of a recommendation.
