For reasons that are beyond me, French cinema seems to come with movies about such controversial subjects quite often (although they also produce more "mainstream" movies, believe me). If you are willing to watch a movie dealing with love, sex, AIDS and death and where the limits between good and evil are systematically blurred, this one does quite a clever job. If not, you have been warned.
P.S: Don't believe all this is normal behaviour in France...
