Listen, if you know the title, you know how this story plays out. What really sinks this doc is that we, as an audience, know where this is headed. It's spelled out for us in the name. Despite this, the doc takes nearly an hour (solid 58 mins) before it gives the reveal. This doc doesn't even hit the 90 minute mark so how can you wait more than two thirds of it to get to the real story?
By the time I found myself actually interested in what was going on, there were 11 minutes left. My expectations were low going into this movie and yet it still didn't manage to meet them. They didn't even bother discussing the three actual perpetrators or how they fit in to what happened. Nor did they leave any time to discuss the trials except as a footnote at the very end. There's likely an interesting story here but this was not the way to tell it.
