By skyforbes The ending is so devastating because it shows that survival doesn’t guarantee a return to the life Chuck left behind. 4 years of isolation, Chuck finally coming home expecting some sense of normality, only to find that the one thing keeping him going (Kelly) has moved on. The final crossroads scene is heartbreaking because Chuck stands there by himself alone, after everything he’s endured. Alone like he was for the last 4 years. Idk man this movie makes me cry every time
