I just watched this film in the cinema, and I got to say, at the end I was walking out of the cinema with a big smile on my face. Not because I had seen a very good movie, but rather because I found the sheer randomness of the narrative pretty funny.
The movie tries to give a psychological motivation for the actions of its protagonist Jeanne, but what it actually accomplishes is very a fragmented sketch of Jeanne's life. There seems to be some causality in the narrative, but nowhere is there real motivation for the plot events. A lot of loose ends are left untied, and I kind of wondered why some things were even shown.
The film style is sloppy and unimaginative. The director tries to establish a motif by repeatedly showing shots involving a metro, but the shots don't really fit well and its only purpose seems to be to remind us of what the movie is about (if you knew before going to see the movie). The editing is fragmentary and mediocre, the cinematography seems okay.
I wouldn't really recommend seeing this film, though as I said before, I did enjoy myself, if not really for the reason I was supposed to.
