I was very surprised how well acted and directed this revenge movie was. It is very realistic and very disturbing. The torture scenes were the toughest and most up close I've ever scene, so beware. I don't know how they did them but they were super realistic. Do not watch if you are a sensitive person. Sarah Butler's acting was superb and believable. There are no slow or boring parts and you won't be able to stop watching. I've since watched the second and third sequels. They are also very good.
