As people keep calling this a Christian movie, it's not. As an atheist, I can say this movie is not preachy nor does the religious parts bother me. While there are a few moments about Christianity, it's not the central point of the movie. The central point is child trafficking and child abuse and how it's a billion-dollar industry. The guy does look to his god, but as an atheist, you can just say this guy is looking within himself to be a good person.
Some of the acting is a little over the top. There could have been more action at the climatic scenics but I understand they didn't want it to be the central point of the movie.
I highly recommend you watch this movie. It will make you feel something and hopefully, shine a light on the horrible reality of child abuse and trafficking.
