If this were fiction, the movie is well done, but the historical inaccuracy is outrageous. The answer to 1967's Bonnie and Clyde film over-romanticizing the criminals should be accuracy, not aiming for "two wrongs make a right". It's a shame, because there are aspects of which the film does go out of its way for interesting authenticity. But then to so grossly, surely intentionally, distort events to make the bad guys seem more villainous and the disgraceful Hamer and company more buddy cop heroic is appalling.
It feels like someone made a whole movie about Greedo shooting first in Star Wars to supposedly help the Han character, but worse, of course, since this is about actual people and events.
I will grant this: if the film was intended to give us Hamer and Gault's possible perception of events and everyone involved including themselves, that's pretty interesting. The problem with this for me is that most viewers would have no way of realizing the level of misperception being presented.
There needed to be more of a reliable voice calling the main viewpoint into question. Such a nuanced presentation, beyond service to authenticity, would actually have been more interesting and entertaining. C'mon, Netflix. Do better.
