this is one of mine. another is children of men. both are so grim, almost painful to watch. maybe also stalingrad, although it isn't as good a film as the other two. watching all 3 in a row would require prozac.
Finally someone mentioned "Threads"; thank you, Darius6. I rarely refuse to watch a good movie again; nevertheless "Threads" left me shaking and wanting to go down on my knees and pray.
Another one where I either couldn't finish the book nor watch the movie all the way was "1984".
Carnal Knowledge Cries and Whispers Last Tango in Paris
There are others, but I'm just submitting a short list. Have never been able to watch these three ever again.
However, I have seen The Pianist 4 times on TV. Very moving, very well done in most ways. Sometimes I think the Nazi topic has been done to death, but then something this good comes along. Far superior to Schindler's List or to Inglourious Basterds. My personal opinion.

I tend to rewatch great movies even if they are depressing or dark.. but one that disturbed and depressed the hell out of me was Irreversible. I guess you can call it great because it succeeded in doing what I think it was trying to achieve. Some movies you just watch once, no matter how good they are
I'm absolutely stunned that no one mentioned "The Bicycle Thieves". Not only is it one of the greatest movies I've seen. It's also by far one of the most depressing. And I mean right off the bat.
It was one of mine too...watched it the very first time when it came to theaters in 2002; since then, in here it's on TV every 27th of January, yet I never ever had the guts to watch it again. I'm gonna do it today.
Another one is "Martyrs", as someone else already wrote...and that I will NEVER watch again.
