When I borrowed this particular film from a friend I was expecting something rather similar to the 1989 horror comedy "Parents" and "Grandmother's House" does start out like that aforementioned film, but in a much serious and second-rate manner. It does go for that psychological edge, but it lacks the finesse and deft touches to carry it along. It's quite straight-up, nothing subtle. But then it takes a sudden turn into mundane psycho-killer territory with one very long chase sequence, to only turn back on itself revealing one very demented, if sudden revelation that comes out of nowhere and which I didn't see coming. By this you can say it's a makeshift of ideas that cheaply executed (there's a made-for-TV feel), but does have its moments.
After the death of their father, David and his older sister Lynn go to live with their grandparents. One day David sees his grandparents dragging a bag, which looks like the shape of a person and strangely enough a body is soon discovered near the lake by their property. Suspicion arises for David even more, especially when he sees them dragging a body of a drifter lady.
Going further into the oddball plot can destroy certain twists. The stilted script has some dumb dialogues and ridiculous inclusions, but it stays entertaining. Suspense kind of comes and goes, being the highlight of a rooftop walk. So does the atmosphere, where it's the music arrangement that keeps it fairly eerie. Performances are ideal with the unnerving Len Lesser giving it his all. Eric Foster and Kim Valentine acquits themselves well enough as the two kids. Then there's Brinke Stevens in a small, but important role. Director Peter Radar does a steadfast job and producing this enterprise happens to be Nico Mastorakis ("Island of Death" & "Blind Date").
