The working in of the flashbacks made a big impression. They were not necessarily in historical correct order, but as the woman remembers them. The flashbacks always revealed enough of the story in Nevers, that kept you busy trying to slowly piece together what happened.
I remember having an expected pay-off moment, when the villagers cut her hair. There was also dirt around her mouth in that scene, which I couldn't figure out, maybe the dried blood of her lover.
Beautiful music and editing. The documentary part in the beginning was rather shocking and finishing with a view from "space" talking about the delta of the seven rivers.
