Query: disappointing ending

John Knowles does a good job of developing Lou Colfax' character, only to waste it with a rushed, so-so resolution of this man's troubles in the end. He does present good insights about war, life in New England, and early 20's angst. The various characters around Lou are also very interesting. It was only at the end that I felt let down.
