It brought a tear to my eye so it's a an automatic 10. Based on a true story with a few differences from what actually happened, yet spot on overall. I hadn't heard of the story before watching the movie which is what made it an even better experience. Acting was well done and what you'd come to expect in these kind of films dealing with kidnapping/ rape,etc and as a parent myself you can feel the anxiety in what you would go through ever having to go through such a situation.
I can't stand giving spoilers so I won't go into exactly what happens, but the execution of the film is well and worth the hour and a half investment.
