That's the first movie I thought of when I read the thread title. It's been a few years but I remember this film being super depressing.Wait, fourth page and no Manchester By the Sea? Does that not count or just not bleak enough? Fantastic performances in that too, Casey Affleck can be top tier when cast in the right role.
This is on the list of beautiful movies I will never watch a second time. I do suggest it to people for a watch, but you need to be in the right head space.
