I chose to see this film for my French & Italian Cinema class Term paper during the Fall 2008 semester at BYU. (I highly recommend the class FREN 217/ITAL 217)
Le Fils  (France., 2002) 
From the very beginning, the main character Olivier  shows a strong interest in a boy. The reason for this interest is not  known until it is revealed by Olivier’s ex-wife and mother of their late  son. The film presents the simple yet complicated story of a man  meeting and interacting with his son’s murderer. Unlike criminals  presented in other films, the murderer is a simple boy and not a typical  troubled or malevolent being. It seems the only complexity to this character would be the fact that he is an unintentional killer. Olivier's ex-wife asks him a question which any one would ask; why has Olivier taken in Francis beyond the necessary bounds of a mentor's duty? What are his intentions? How can he interact so easily with this boy and show no anger or rancor? It takes a long while and patience to find this out as it is unclear throughout the beginning of the film. It slowly becomes clear that Olivier had an unsatisfied curiosity about the  character of his son’s killer. He looked for answers to the obvious and unrelenting questions that unsettled him; "Why did he kill my son? How does he feel about it?" How  is it possible for a child to become a murderer? There are so many  reasons that might come to one's mind, but the Dardenne brothers show how it may be  less complicated than one thinks.
The Dardennes amazingly step away  from the much exploited theme of revenge and instead present a story of  forgiveness through a nontraditional style of film, at least nontraditional to the mass audience that creates big box office revenues.
The Dardenne brothers  do an incredible job with Le Fils  of portraying exceptional  circumstances in such a simple way that  makes the whole story  believable. The plainness of the film’s  presentation through long lasting shots and its framing are some  aspects of the film that empower it. There is a deepness to the general  image of the film that gives way to subtle visual discoveries. One discovers certain details, certain diamonds in the rough, that gives the film greater significance. By allowing to make these findings, the Dardennes make the viewer an active participant in uncovering the characters' motivations, their concerns, and their desires. Hopefully the viewer will independently recognize the film's intention to enlighten with a compelling story about forgiveness and ultimately create compassion for a fellow sinner.
Jean-Pierre and Luc Dardenne’s choice of actors is another credit  to them. Olivier Gourmet’s  acting was very simple and neutral which was a necessary balance for the emotionally charged situation. Anything more would have been an excess.
The same goes for Morgan Marinne who plays Francis, the murderer. There  was little or no emotional expression from his part as well. Both  characters expressed neutrality, from their looks, movements, and voice.  In the film, Francis says that it’s a shame that he spent five years in  prison, but he is unaware of all the consequences brought forth by his actions. It occupies his mind and  he feels guilty about it, but he doesn’t fully understand the impact  this had on another person; the boy’s father.
The actors appropriately  bring to life two heavily burdened characters. The father, who is haunted not only by his son's death but also by the killer's presence, is finally at peace and able to forgive. The murderer comes to full terms with his actions and in the end becomes a son.
I later talked to my professor about it and he  pointed out how it has strong Christian symbolisms and undertones like  the fact that Olivier is a carpenter, and the whole story revolves  around sin and forgiveness. The movie poster is  symbolic for Christ bearing the cross. Christ bears that burden and  Francis bears the burden of having taken someone's life.
“Now  you must absolutely stop reading and go see the film. Walk out of the  house today, tonight, and see it, if you are open to simplicity, depth,  maturity, silence, in a film that sounds in the echo-chambers of the  heart. "The Son" is a great film. If you find you cannot respond to it,  that is the degree to which you have room to grow. I am not being  arrogant; I grew during this film. It taught me things about the cinema I  did not know.”
-Roger Ebert
Rotten Tomatoes gave it an 88% on the Tomatometer and the consensus was "Austere, finely crafted, and compelling."
I realize it is a tough movie to watch, but it was worth it. At least for me it was.
