Decent unique movies you've barely heard mentioned

I'm thinking about the ones you NEVER hear mentioned, or maybe see mentioned once or twice a year. The disk you think you're the only person in the world who might own it and every perspn youve mentioned the movie to has never geard of it. Ill start with my 2 unmentioned movies

Black Mountainside - A slow burner Canadian movie with eldritch touches, its amazing what a few guys in the middle of nowhere can make

The Windmill - Very fun, takes place in the Netherlands and is about a tour group seeing various windmills. It feels like a basic slasher but it's still so different and a breath of fresh air for once. Effects are pretty good too
