The film is ok
the pacing is fine, there are really good scenes and Jean Gabin is great in this
However there are a few things that i find impossible to overlook such as the moralist overtone the film has as it shows absolutely no mercy or reedeming features in Catherine even though she has no fault in the way she was brought up and the circumstances in which she is forced to act the way she does, instead the movie apoligizes André's mother that harasses her employees, kidnaps and whips Catherine. Its like im watching an perfectly backwards adaptation of marquis de sade's Justine.
Besides that the one major plot flaw in my opinion was the fact that Gerárd always used to carry his dog around, that by itself warned me 30 minutes prior to the ending what would happen and made the movie significantly less believeable
