Plot = Memorial Valley Campsite has just opened for business even though it's far from finished. A bunch of campers set up camp, unknowing of the terror that awaits them in the forest. You see, a Tarzan-like forest boy does not approve of the recent changes in Memorial Valley and has decided to start killing the campers.
Well I can say that I've definitely never seen a movie about a killer caveman before, cheesy for the first hour in other words just ain't that good only one person dies during that time, however once the movie gets going the last thirty minutes is pretty entertaining as should they be seeing as how fourteen people get killed in the final half hour of the movie.
This is one of the last backwoods slashers that we got from the 80s and I think it's pretty safe to say that this was one of the movies that killed the trend. The movie is obviously very low-budget with a bunch of incompetent actors and an even more incompetent special effects team. The gore effects are ridiculous. Memorial Valley Massacre is far from a flawless film but as I said before, the final 30 minutes kind of make the first hour feel worth while.
All in all it may not be a very good movie but it's quite enjoyable during the last thirty minutes which is why I've given a 5 instead of a 4.
