Just to add a little something on my mind.
Of course everyone is speaking everywhere of the real life aspect of all that, and the human consequences and all, that's understandable as there are 2 men jailed for life.
Now, speaking about the documentary, art wise.. If Steve did it. It's even more fucking incredible lol!
To me the whole documentary is genius in its david simonish way to show how the society can crush a family with its infinite complexity and idiocy. It's also unbelievable in term of pure crime intrigue. From that later point of view, if the film makers did so much to convince everyone, and themselves, that all those proofs were fake.. That's amazing lol.
Cause chen you thinkk about it, there are soooo many proofs, and we are all convinced the more proof they find, the more innocent Avery is, cause it seems soo big and obvious. Now if all those proofs are true. The key, the blood etc.. All those evidences and millions of people convinced themselves to unvalid all of them, that's fucking incredible when you think about it. That's a thing of beauty in itself!
Now i still can't really believe he did it, cause there was no motives and it doesn't make sense. Now that's troubling that everything, in the documentary, that could lead to think Avery is a "monster" (the cat fire, the violence with his cousin and his first wife..), and that would make the case so much more believable.. is said super quick. They never come back on the early episode informations about Avery's youth. They talk about the mail exchange with his wife in prison, that is pretty violent. They say something like "it escalated quickly but nothing special". Same for the cat "Every said it was an accident". The cousin and the car incident, the same. All of that is seen super quickly and they never really come back on it. And our perception of the case changes a lot cause of that. A documentary in the other direction would have easily showed Avery as a deranged, violent and dumb man, and then there would be way less will, from the viewer, to see every evidences as ridiculous.
But that doubt is what makes the film for me, narrative wise.
