I found that film quite moving at the end, where everyone in the middle of fighting their pointless battle hears the cry, and they all stop. They now *know* that's hope, even if very slim. There's a chance, and that matters.
There is humanity in all of us. And for all the attention and fuss made about how bad we can be - and holy moly can humans be bad - there is an equal measure of beauty and grace right there in us too.
