Seven months later they ship Charles' corpse back home
This has got to be the saddest and most horrifying aspect of this story. Having to go through this gut-wrenching ordeal of searching for your missing son/husband, you finally are dealt the heavy blow of his death. Anger, sadness and despair ensue, but at least there is closure. And with time closure can help the bereaved deal with sorrow and go on with their lives. It can take months or even years. Some never get over it emotionally.
But after 7 months and returning home, then, to add injury to insult, his corpse is sent back home in a wooden box. How horrifying that must be. What are they supposed to do with his decomposed remains? It's too horrifying to look at and it is way to sad to have to deal with it.
To me, that was one of the saddest endings I ever saw in a movie.
