Don’t get me wrong, storytelling is important, and these kinds of films are important for the sector of the population that still doesn’t get it, and still needs to hear the call to action, but I’m not sure I would call them documentaries.
Our brains have evolved to be attracted to stories and story telling. I'm not exactly knocking it down when it comes to social situation (or even business/advertising), but when it's being used in the context of presenting factual evidence it's being used as a brain-hack to propagate an agenda.
