curious why anyone would make this movie, let alone watch it?

because it was good.

You just don’t get it and never will

I'm confused as to why you ask..
Do you feel the same about all films about war or terrorism or conflict or internal crisis?
How about films about 9/11 or the rape of Nanking or the Holocaust or Bosnia or the Armenian genocide or Rwanda ?
Sometimes it's good to see why these things happen and to see the human element behind the headlines.

Please explain.
