I thought Sound of Freedom was going to be difficult to watch, only because it brings to light the atrocities associated with the trafficking of children. It is based on the true story of a federal agent, who in the regular practices of his job, saved a boy who was being trafficked. Of course, such scenarios tug at your heartstrings and make you feel sick.
The concepts were hard, for sure, but it is tastefully created so that you don't have to endure what is implied, and this is a wonderful movie. "Wonderful" for the storyline, but I also use that word because it does bring an awareness to the viewer of how fast this crime is growing and why. The answers are not pretty, but things cannot grow in the light as well as they can in the dark, so awareness matters.
