I've seen a lot of mixed reviews. I think people are missing the point here. The point is that the brother who committed suicide was writing a story about fighting a losing battle.

The main tension is whether or not suicide is selfish or selfless. However we interpret it, the suicidal brother certainly saw life as a losing battle. more
