I was really excited about seeing this film, after reading so many 5-star, rave reviews from both critics and the general public. The story and subject matter sounded very interesting, and I was expecting great things. Unfortunately, for me, there just wasn't enough substance to the story, and the constant flashbacks were distracting. Other than a couple of violent scenes, there was no excitement, no plot. It just seemed like a long and pointless story about a disturbed young woman and her well-meaning sister. In the end, we are left to wonder if she was ever able to get well and leave the demons of the past behind her. Very little story and no clear ending....that's about all I have to say. One more thing: Elizabeth Olsen did a fantastic job in her role, but I honestly did not find myself rooting for this character as much as I wanted to.
