Confused by reasons for disliking this film
I've read some comments and the ones panning it for anything other than political reasons seem odd. I think too many people need to have a happy ending, or a coherent ending or something completely explained to them, because they are devoid of complex thought. This movie is dark. Like Laugier's Martyrs, this movie isn't a feel good movie. It is brutal, honest, but most of all it asks us what is more important. It is a social commentary on everything that is wrong with our "cycle," but explains that we can not just decide to change it for people.
I also thought Biel was brilliant. The movie was extremely careful not to leave any major plot holes, aside from one, which I'm assuming we're supposed to understand (Why Christine would help....was she one of the first?). The ending, in my opinion was perfect, because after stating one side, with Biel's explanation to the Mrs. Johnson, it is Jenny's final three words that place the question to us. Very thought out film, especially the script and very carefully done as not to poke fun at any socio-economic groups, but to show empathy.
It's too difficult a movie to pigeon-hole with good or bad, because there are things about it that should bother us. Like Martyrs, you aren't going to leave the theater or your couch with a warm fuzzy feeling and that is what they intended.
