Very good performances from Ellen Page and Catherine Keener for quite an empty movie. Could have been done much, much better with a proper direction and script.

Nice point of view of the torturers. It'd be easy to just show them as evil demons having fun doing bad things. I liked how the script portrays what they might had thought, sometimes very subtle. As the guy who had a crush on her and was rejected while she was still free, and later marked her. Paula who was pregnant and projected all her issues on Sylvia and wanted her to be seen as a prostitute. And Gertrudes herself who was old and ugly and probably was envy of Sylvia. Such possible motivations were shown without stimulating us to feel anger for them.
