Forgettable, by-the-numbers 80's slasher in the woods, which is saved from total mediocrity by an unusually high body count and a fair amount of tongue-in-cheek humor during the first hour. The beautiful forest region of Memorial Valley is being turned into a fancy camping site by a rich business man. Various campers begin to arrive, even though the site is far from ready yet, and so does a primitive caveman killer. At first, it simply looks like the scarcely dressed Tarzan Junior is butchering campers because they're messing with the ecological balance in Memorial Valley, but there's also a personal vendetta. He has been living in the deep forests for almost twenty years, and his presumable father who just happens to be in charge of the campsite never managed to track him down. The murders in this low-budget slasher are pretty imaginative, albeit completely gore-free and rather tame. A couple of insufferable characters are massacred with ingenious booby-traps (pits with stakes, falling trunks, ...) but the cave boy himself is one of the most UN-menacing killers in the history of horror movies. His total lack of evil charisma is even funnier when a supposedly tough and macho biker runs away from him, screaming with fear like a little girl... Multiple other reviewers also pointed out already that it's quite remarkable that our Mowgli has the knowledge to blow up a caravan without ever having seen one before in his life! There are loads of amusing little stupidities in "Memorial Valley Massacre" and they effectively distract you from the total lack of tension, plausibility and gore. Robert C. Hughes' previous movie, the fascinating survival horror flick "Hunter's Blood", was a lot better and more tense but still this quickie is recommended to undemanding horror fans. The character of the retired military general (played by veteran William Smith) is truly cool.
