My review was written in December 1987 after watching the show on United video cassette.
Originally titled "Nemesis", "Forever Evil" holds the dubious distinction of being perhaps the longest made-for-video horror effort to date. Bloated running time features a few good ideas and acceptable gore effects, but definitely would have been cut if theatrical release were envisioned.
Story is derived from the popular mythos of H. P. Lovecraft (not credited, with no screenplay credit displayed), as various survivors of encounters with a Grim Reaper-styled caped monster team up to find and fight some supernatural entity. Referring to mythical books such as Lovecraft's invention, "The Necronomicon", they deduce that the ancient god Yog Kothag, exiled to a distant star system, is being brought back by cultists to take over the Earth.
Pattern of murders on the map (pic was shot in Houston and Cold Springs, Texas) forms a pentagram, leading our heroes to descend upon Nash Realty for a bloody climax. It turns out evil realtor Nash (Howard Jacobsen) is over 100 years old, using as his zombie assistant a guy he killed over 60 years ago. Hero Marc (Red Mitchell) is turned into a zombie at film's end but stabs Nash to put a halt to Yog's Earth takeover bid.
Best thing here is an intriguing puppet designed by Luis Ibarra representing a monster baby, which recalls the fine Rick Baker creations for "It's Alive".
