I don't understand the hate this film is getting. I thought this was a really good western thriller with great acting, likable characters and of course a nasty villain (which is what a film like this needs.) I really liked the music to this as well and i would definitely recommend this to others (15+).
It does contain references to sexual violence and the overall theme of kidnapping the main characters daughter for the use of prostitution. There is lots of violence (sometimes gets graphic, with lots of blood), with use of guns, arrows, knives and more. But overall this a a great film and i really enjoyed it and it should be fine for a mature 15 year old.
