The Son is a movie about forgiveness, and how the very act of forgiving propels you forward as a human being. And to not only forgive the person who took away your son, but to become a guardian, a teacher to that person is an act of grace. Olivier exhibits this grace throughout the movie, but it is a grace that is not evident by just watching him on a day to day basis. You have have to follow him, listen to him, be with him constantly and understand his circumstances to realize this. I suppose, in a way, that many people possess this grace, but its hard to find it in them if you can't follow them around with a camera. Olivier, on the surface, would not seem like a very interesting person if you saw him on the street, or worked with him on a daily basis, and the boy seems like a dolt, but this movie makes them so interesting, so compassionate, not as characters, but as real people. It teaches you to look beneath the surface of things, of human beings, and if you look hard enough, you'll find beauty everywhere.
