I think it is an engaging and thoughtful movie - the kind that you keep thinking about, long after you have finished watching.
The plot deals with the central character's coldness in relationships with people around him. He is definitely gifted in what he does. He is sincere and hardworking. People around him tend to be friendly and caring. But it seems our guy has some intimacy issues he can't go beyond a certain level.
I am not really sure as to what message did the movie want to convey. It can't just be - if you are cold in nature, you are a loser. I don't think Stéphane was cold by choice he couldn't just change his nature so as to make others happy. I found it odd that a person of such nature would speak with frankness and openness about these issues the way Stéphane tells Camille in the restaurant. His friendship with Hélène also seems unexplained - what was the basis did they expect it to go further?
What struck as peculiar was attention given to details on mundane activities - like the craftsmanship involved in making musical instruments or dealing with the restaurant manager. In some ways, these elements helped in keeping one occupied and expectant of things to come.
Daniel Auteuil's portrayal of Stéphane was very natural. Always immaculately dressed, the way he interacted, sometimes with a smirk on his face - it made you empathize with his character. Also at times you felt like saying - what's wrong with this guy? probably the kind of response director would have wanted to evoke from the audience. Emmanuelle Béart has acted brilliantly and looks amazingly beautiful. André Dussollier also put in a strong performance in his portrayal of Maxime.
Dialogues are thoughtful - but at times their gravity made you feel that these are not the most natural of conversations. Cinematography is splendid with close shots of characters and focus on eye and facial expressions.
