I didn't expect to be so moved by this documentary. The first 20 min or so, I had doubts as to the depth of the film - but as it progresses, it builds suspense and substance. The twists and turns are interesting but the real insight is how life is more complicated than good vs bad, and how people can't be categorized this way, and if you can see that, it can change your life. Truly beautiful story about the power of understanding, and love.
