For me, 2 things come to mind; Berserk & the Long Walk

Berserk may sound controversial, but I just didn't have a good time watching the 90's anime. I felt angry while watching it. I just didn't like the characters for how dickish they were (especially Guts & Casica) and the setting was too miserable for me. And some of you may go, "but the comic is 10x better" (I know it's manga, I'm just calling a comic to piss of people) I also just don't like dark fantasy in general, since they're edgy, pretentious, and worst of all... they're ugly. There's a reason why I never played the Dark Souls games, outside of the difficulty

The Long Walk movie is really well made movie with amazing acting. But man was it a miserable movie to go through. Seeing all those kids getting shot by soldiers for being slower was painful to watch.

Side note: there's a lot of critically acclaimed stuff I like (Cowboy Bebop & the Dark Knight). It's just that entertainment is so subjective that it's not mutually exclusive to writing.
