text: Based on Ray Russell's dark bestseller, this John (WATCHER IN THE WOODS) Hough-directed bust has little going for it.<br /><br />Though it does not lack gory violence, it lack narrative sensibility and "characters".<br /><br />The "Incubus" of the title is a demon endowed with a mammoth penis that shoots red sperm into vaginas during intercourse -- or, to be more precise, rape.<br /><br />John Cassavetes, moonlighting from his successful directing career, is convincing as a doctor who questions the circumstances of the bizarre attacks on young women.<br /><br />Horrific possibilities of the victims spawning demonic offspring are not considered -- and neither is the audience's tolerance for slow moving garbage.<br /><br />The script's reluctance to explore the dramatic repercussions of a fertile premise exemplifies the major problems with this vapid Big-Schlong-On-The-Loose exercise.
