For those who know nothing about this film

Rating: 10/10 (22 December 2016)

About a third through watching this streaming video in our small TV room, we put it on pause, and I said to my wife, "Do we want to continue to watch this, it looks like it just may be too painful." We hesitated, and then decided to go on.
Maybe, you are reading this to decide whether to view it; it's on Amazon Prime, at no cost, and may be on others. So, let me say it was one of the most moving and genuine films I've seen in my now long life. While most reviewers eschew "spoilers" that give away the plot, in this one, a review has to do this to some degree.
We were lucky,as we watched it unfold with the first half hour not knowing what would transpire, seeing it from a child's limited view given his unusual circumstances, and gradually realizing along with him what they were.
Therein lies the films brilliance. Don't get anymore details, just watch it.
