Os Assassinatos de Cheshire

I'm not sure what the theory behind this doc was supposed to be (as in, why was this made other than a rehashing of the facts)... I'm so jaded after watching so many documentaries that I believed that it was going to be a turn of events and the husband was going to have something to do with it, but no... It's just a straight retelling of a horrible horrible crime—nothing but the facts, ma'am. Was it to show that the Cheshire police were so inept that they should be held accountable? Was it to advocate for right-to-die laws? Who knows. Neither was presented with enough impact to make the viewer feel like that was their intention. The narrative was all over the place and all I got from this doc was a feeling of hopelessness.
