Beatrice Dalle, who made her screen debut as the title character in Betty Blue (1986), gets a showcase role in this 2009 French drama, as a despondent, middle-aged mathematics professor clinging to her college-age nephew as she drinks herself to death. The promise of incest hangs over their story, but writer-director Patric Chiha is more concerned with tenderly observing their ardent, age-inappropriate relationship, in which the wisdom of experience seems scant recompense for the potential of youth. In French with subtitles.
