Mainly just this part:

Franck (Johan Libereau), who takes advantage of her for his sexual pleasure. When she walks out of a movie leaving Franck feeling angry and deserted, she goes to his house to try and talk to his mother. . .

...that it's misleading to say that about Franck, because she wants it. He may seem aggressive, but that doesn't mean she didn't seek the sex just as much herself. And as I recall she was at the hotel for the sex, and then went downstairs and talked to his mother the next morning. The way you tell it seems a bit off in the nature of the event and the sequence. But I may be wrong. However Marcia L, a lady I have talked to at the screenings who loved this film and obviously "got" it much better than I did, did not think "takes advantage of her for his sexual pleasure" gave the correct impression. She said Prudence wanted to go to the hotel to talk to Franck's mother, so the sex may have been partly an excuse, but she didn't feel Prudence was taken advantage of.
