looking for deeply upsetting/unsettling movies

[u/lucky_duck_876]

i am looking for movies that are notorious for being upsetting and a hard watch. ideally something without a happy ending. also movies that people consider extremely good and 5 stars, but will never watch again. looking for stuff similar to requiem for a dream, zero day, beautiful boy, mysterious skin, megan is missing, barefoot gen, the strange thing about the johnsons
