This is undoubtedly a beautiful film, with every shot as ravishing as a Renaissance painting, and the music too is heart-breaking, but at the centre is an emotional emptiness that is profoundly disappointing...
Gerard Depardieu is the ageing Marin Marais at the court of Versailles and he narrates the story of his relationship with the composer and musician St Columbe who refuses to come to court. As a boy Marais is involved with the St Columbe family, father, and two daughters, one of whom has his baby.
The problem with the film is that the relationships lack any chemistry and the narrative voice which tells the story replaces a true dramatisation of emotions: this is a story which is overwhelmingly 'told' rather than 'shown'.
That said, the music is ravishing and speaks far more than the dialogue (and the unspeakability of some things is certainly a motif here). So overall I enjoyed this film, loved the music (and would certainly buy the soundtrack) but wouldn't watch it again.
