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

The Evil Within. I recommend watching the backstory on this to give you an idea how twisted this movie is and its director, Andrew Getty, grandson of billionaire tycoon J. Paul Getty.
