(a Breton (celtic) chemist serial killer with an ecologic leitmotiv makes friend with a young cop - Depardieu son. This later will understand that the one he befriends is the one he is chasing...) Well, when first playing this film I thought it would be one of these french movies whose over-sophistication tries to compensate the scenario's dumbness, and even if the storyline is quite basic I must admit I was wrong. Perez's performance is brilliant, and the global montage gives way in this quite indigent story to some personal interpretation that the fans won't miss. Nothing to do with french independent film, if such a thing exists, but a nonetheless not so bad film that can fit a relax evening meeting with a pizza. Of course serious ecologists will surely get infuriated with the mess that is done with their ideas...
