After watching this film I can't quite decide how I feel about it. Jean-Claude Brisseau might be a genius. Or he might be a flawed old pervert like some of his controversies would suggest. Regardless of reality there isn't much of the perverse in this one at all. The nudity isn't there to shock and there isn't nearly as much as some of his other films.
The whole thing is equal part's old man's fantasy and a hopeful wish for some meaning to existence. Or at least that's what I came away with. I think every man who knows he is past the time when he can easily attract the attentions of a young beauty has had at least a fleeting fantasy of a relationship suddenly appearing. Maybe it's platonic or maybe it's not. That would depend on the one doing the fantasizing.
At any rate this particular relationship is platonic, which makes it more believable. Virginie Legeay does an admirable job of making us believe that she really cares for the old man of letters. And the director, Claude Brisseau, does an admirable job of portraying a man who feels that he is nearing the end of his cycle.
My indecision comes from feeling some irritation with the meandering philosophical discussion while at the same time feeling somewhat uplifted. I do think it is a very good film on balance.
Basically I think you should watch it for yourself. I can't predict how you will feel about it but I think it's worth the time to find out.
