This is a slow film, and I find certain takes to be unnecessarily long. For example, the opening scene with Jean, the male lead, noisily working with his jackhammer can be shortened with no impact to the story telling.
However, this will be all the fault-finding I can do. The acting from the three lead actors is great and the music, though sparse, is appropriate. Jean is a quiet, responsible blue collar worker who takes care of this wife and son, and shows great love for his ageing father whose feet he often washed with care and tenderness. He is a simple person and a good human being. In fact, there are no bad characters in this film. What it is about are choices in life, and there are no right or wrong choices here.
When fate brought Jean to his son's teacher, Veronique, who gives him a taste of another world he had no previous exposure to, he was enchanted. And this enchantment transforms itself to a fierce love for her which is all consuming. Jean is shy, and looks down to the ground most of the time. So moments of intimacy are subtle and subdued. But you can feels the intensity of Jean's feeling and what it does to his mind.
In the end he has to make a choice: the love of his life or his responsibility to his wife, son, and ageing father, all of which he care about. No easy and simple decision here. And it will be difficult to predict what we will do when we are in his position, knowing that either way there will be no happy ending for all.
But, hey, such is life. One can argue the very confrontation of this choice makes life worth living. This is simply a great romance story of very real, ordinary people told without fanfare. A great French cinema experience in my opinion.
