No Country for Old Men. The ending is so dark that people were mad at it because it just....ended. No resolution.The bad guy gets away, one hero dies and the other gives up.
He also dies off-screen.Now I haven't seen that film but any script writer or director that has the hero losing or the main character/title role die and the villian winning is really brave and a quality writer/filmmaker if they can make it work within the story. It is so different, unexpected and not cliched if you will.
Event Horizon was a great movie Addendum. I thought Sunshine was pretty dark too
Gina Davis was crap though. Hot, but crap.The fly's a cool movie. Jeff Goldblum does a good job of making the charecter more convincing in loosing his humanity.

er Untergang(The Downfall).
