Why is Charlie 'filled with hope' at the end of the movie?
I don't "get" the ending. At the beginning of the movie, Charlie is bitter and depressed, unsatisfied with his looks, his writing, his clothing, his romantic life (or lack thereof) and his life in general, at one point describing himself af "fat, old, bald, repulsive". Over the course of the film, he gets rejected in various ways, shouted on by McKee, sees his brothers succeed in everything he couldn't, disappointed by Orlean, and in the end, his brother dies, in part because of him. So almost nothing changed, and what did change just got worse. If anything, I would expect him to be even. However, he seems happy and hopeful.
Can someone explain this? It makes no sense to me.
