Does anyone know a good psychological thriller? No splatter or mere scare, but maybe with a good story. Should be on Netflix and co. Be available.
"The game" (is available on Netflix) and otherwise "Split" (can be bought or rented on Amazon Prime. Maybe it will be free. It's really worth it.).
I've already watched the game. It was really good.
So spontaneously I would think of "Memento", "True Story - Game for Power", "In the Twilight" and "Psycho" (which is a bit older, if that should bother you).
For series, I'd suggest "Die Einkreisung", it has a great storyline and the atmosphere is perfect. However, there's already a little blood flowing.
I think of Strangers from Hell
It's a series and I can't yet exactly what genre it belongs to (I've watched episode 1 so far), but the atmosphere of the series alone has a lot more to do with the psyche and the characters. Nothing serious has happened yet and still had to stop the series again and again.
So I think it's really crazy, but very well done.
