Very well acted. Good soundtrack and photography. Excellent integration of the correspondence with the rest of the story. From the perspectives of the history of scientific emergence, identity appropriation and the sexual emancipation of Quebecers, this film is essential and should be seen by as many people as possible, particularly teenagers aged 15 and over. However, the two-pronged production (the relationship between Marie-Victorin and Gauvreau in relation to the mise en abyme of the cast) adds nothing to the film and even harms its pace and intensity, even its depth: one gets the impression that the director does not trust her audience.
