No, the movie that I'm stealing the discussion title from probably doesn't qualify, but what are some of the MOST DEPRESSING movies you've ever seen. Now, we don't mean ones that were disappointing and didn't live up to the hype. We're also not talking about films that are simply 'dark', as many dark movies can actually be quite uplifting, even funny.
We mean movies that make you want to curl up into the fetal position and weep uncontrollably for a while. Bleak, austere- the movies that suck joy and hope out of you like you were a Capri Sun pouch.
Some of my examples:
Solaris (the original, though there is a ray of hope in it)
