Brutal and very hard to watch though this may be, it's well worth watching. It's horrific and unsettling, that one person could do something so awful to someone, let alone a whole group of people, but this film does an excellent job of telling the story, based on a real event and testimony from the trial of Gertrude Baniszewski, a single mom with way too many children, who has absolutely no excuse for treating a young girl (Sylvia Likens, played by Ellen Page) the way she does.
