It can never be a good sign when a film's credits don't list any name as "writer". Sure, everybody knows the plot is inspired by H.P Lovecraft's "The Lurking Fear", but even the legendary horror author remains uncredited, and nobody else is mentioned for the adaptation, neither. "The Lurking Fear" is a fantastically horrifying tale, but it has yet to receive a good film version, and this clearly wasn't going to be it. "Dark Heritage" truly is a laughably incompetent late-80s horror dud, but at the same time I must admit it's also tremendously entertaining! Three guys head down to Louisiana to investigate a mass murder that took place at camping ground near a reputedly haunted mansion. Sure, I know they look like drunken perverts on a fishing trip, but they are actually reporters of a newspaper. They spend the night at the mansion, but one thunderstorm and a bit of blurry camera footage later, two of them have vanished and the survivor is blamed for murder. But our hero, Clint, quickly finds two new buddies (two 40-year-old college students) to further investigate the origin of the hideous demons crawling around the Dansen estate.
Now, I know Lovecraft's tale "The Lurking Fear" rather well, and what I honestly can't figure out is why the name and nationality of the spooky immigrant family changed for this version? It always was the Martense family and they came from Holland. Now suddenly, they are the Dansen family from Norway? Lots of the things happening in "Dark Heritage" are dumb and don't make the slightest bit of sense, the dialogues appear to be written by a 4-year-old, and the acting performances are beyond insufferable. On the other hand, the make-up effects are surprisingly gross (the bloke with the half-eaten face is terrific) and the "underground dwellers" look effectively creepy. I enjoyed it, and wouldn't hesitate to recommend it to tolerant fans of cheap and cheesy 80s horror flicks. Still, the film could have used a couple of females in the cast, and the finale is a total letdown, so I really can't give it a rating higher than 4.
