I recently saw “Rampage” from 2009. Its basically a movie where a spree shooter is portrayed as the good guy/anti-hero. Several parts gave me that pit in your stomach, teeth gritting uncomfortable moment. I really hated it. Although I’m not surprised there are sequals I am disappointed and will not be watching them.
I added Gummo and Kids in another post.
Schizopolis is really good and weird but doesn’t leave you as hollowed out as those others.
It’s been a while but I remember Visioneers giving me a similar feeling of bleakness.
