Cluzet is definitely an error of casting in this movie. Totally unconvincing, physically inappropriate, made a fool of himself. Sophie Marceau is enchanting and compensates somehow, but the movie is too shallow and pretentious. It's a shame, because the idea was not so bad: a man meets a woman, love at first sight, can't forget each other, push it almost to the limit, but ultimately there is too much at stake and sex would set them into a path with no return, jeopardizing everything around. They have the strength to stop, backpaddle, leave what might have been a beautiful thing unspoiled to eternity.
Ok, but not with these actors, under this direction, going from cliché-to-cliché in an unconvincingly shallow movie.
