Die unaussprechliche Sünde

Wasn't expecting much from this, to be honest. Discovered it by chance on Prime Video.

I know this genre has been well used, but I found the film to be an enjoyable. Can't believe that I'd never seen it before, as it's some 33 years old now. Yes it does still stand the test of time.

Basically creepy grandparents, living on a creepy farm.

I'd recommend you watch this, if you've not done so already.

Poor David and Lynn! Their father, the only parent they have left, has just died. As a token of their sympathy and concern, Lynn's and David's grandparents allow the kiddies to stay with them. But little do the kids know, their grandparents are actually bloodthirsty killers! ...Or are they? Who cares. I don't, and you won't either. Trust me. This has got to be one of the most painfully uninteresting movies I've ever had the discontentment of seeing. Even with the disgraceful attempts at shocks and unnecessarily complex and nonsensical plot twists, I still wasn't amused. The only thing that kept me watching was an insightful quote made by a boy talking to David: "If I had a sister like that, I'd boff her." Did somebody get paid to write this?!??

My review was written in March 1989 after watching the film on Academy video cassette.

"Grandmother's House" (alternately "Grandma's House") is a clever nailbiter, providing suspenseful variations on a gothic thriller theme. Pic should get a good reaction in the video rental market, bypassing theatrical release.

When attractive youngsters Eric Foster and Kim Valentine go to live with their grandparents following their dad's funeral, Foster immediately becomes suspicious of the old folks' behavior.

He's soon convinced that kindly looking Ida Lee and Len Lesser are murderous crazies preying on passers-by. Cinematographer Peter Jensen's script takes an excellent turn midway when Foster frees a mystery woman (Brinke Stevens) seemingly held in bondage by his grandfolks and she immediately tries to kill him. She turns out to be the kids' long-gone mom (they thought she was dead) whom grandfolks were hiding.

Hectic final rel is loaded with switcheroos, including a surprise incest subplot and morbid final twist. Tightly directed by Peter Rade, pic definitely will keep the viewer guessing.

Both Foster and Nastassja Kinski-esue Valentine score in the lead roles, while Len Lesser is properly ambiguous as granddad. Usually a decorative beauty, Binke Stevens is scary in the character role of mom.

When you come across a movie that no one else has heard of,even amongst fellow horror enthusiasts,and discover it to be both a tense and enjoyable romp,it gives a great deal of pleasure,grandmothers house gave me that feeling.The story itself is nothing to write home about,kids go to live with their grandparents,who have a dark secret, there's a mad woman in the house!! hardly original but then not many films are. But this film has some good heart stopping moments,yes there are some rather gaping holes in the plot and the ending is a bit of a let down but if getting the girlfriend to jump into your arms is a major benefit you can do a lot worse.

Two teens go to live with their grandparents after both their mom and dad die, but grandma and grandpa have a few skeletons in their closet that are about to explode. Film is tightly paced and well edited. It also has many shocking and most important believable twist and turns and once you think you have it figured out, it throws another surprise at you. Very unpredictable. Film also has Brinke Stevens only good performance, though the rest of the cast is so-so. A very little seen gem of a film. Not a horror film like many believe it to be, but more of a suspense film. My Rating: 8 out of 10. I still can't believe this film got so many negative reviews.
