What movie do you is the saddest ever?

I was wondering what the saddest movie ever is? My girlfriend wants to see something really sad tomorow so I need some suggestions. Thank you

I cried a little at the end of "Life is Beautiful." Since it's Holocaust-related, that's a sure thing! And of course, no human can watch "The Dark Knight Rises" without tearing up: I did several times. It's just a work of art! :'''''') Too nerdy for a chick, perhaps...They're not prone to cry out of appreciation for real art. So...

Schindler's List.

Here's a pretty decent list:

The real sad thing on that list is the stupid women shit that occupies the top 5 while the real genuinely good films are relegated mostly to the bottom 10. Women movies are so goddamn stupid.

I am def debating now over Dark Knight and shindlers list. I think I would rather see dark knight again but Ill see what she thinks
