What are the most depressing movies you've ever seen?

happiness is one of my favourite films.
i never felt depressed by it, though. it was disturbing & shocking & darkly, darkly funny.
i felt a little bad about how much i enjoyed it.

ordet is a great film. & it's somber & will definitely make you ponder the futility of life. but i also think it's kinda life-affirming too. sort of like wild strawberries in that sense.

besides grave of the fireflies, which someone has already named, the film that pops into my head is 'cement garden,' the 1993 adaptation of ian mcewan's novel about orphaned children that bury their mother in concrete after her death & try to maintain life as a complete family. it's probably not a great movie in some ways, but it's one of those films that stayed with me from the day i watched it & really impacted me in a way that almost no other film has. perhaps because i could see a bit of myself in the male character in the film. it made me feel bad, but not just because the movie was sad - more that the guy was such a mess, & seeing myself in him made me feel bad about myself, maybe.

not to make this all about myself.

son of saul is a holocaust film that really stuck with me.
dear zachary is a doc that will probably rip your heart out,
