Bleakest film you’ve ever seen?

Sort of in a similar vein to the list The world is hell: hopeless cinema. But to the extreme. (Fight club get outta here!) What for you is the bleakest for whatever reason. For me it’s

The War Zone. The Nightingale. The Whale.

The first two for more obvious reasons(if you know you know) but The Whale was a recent one that left me so depressed and I really didn’t expect it to effect me so much in that way.
