I wanted to reply to this months ago because it actually sickened me and it's like you missed the entire point of the documentary. It doesn't matter what the fuck you feel about these people on a personal level, the fact that this could happen to anyone and is a gross miscarriage of justice is the problem.
Really, to me it's fucking disgusting to basically belittle the fact that two men were labeled as murderers and have rotted away years of their lives because you find them to be dirty people. You should have empathy for them and for anyone that has been railroaded by the justice system in a similar fashion. It's the principle that matters, not the person.
And I don't mean to attack your or anything. I had seen this sentiment expressed back near the start of the year on the internet after watching this documentary and it just really baffles me. I wouldn't want to spend a minute with the Averys at their friggin' automobile cemetery, but I damn sure feel unbearable pain for what they've gone through.
