I think the morbid fascination of the documentary is how "successful" these outrageous, despicable people were able to be, at least for a while. A lot of what they "achieved" was a house of cards and their self destructive tendencies would eventually be their undoing, but the fact that it happened at all is scary. Even more scary is that only one of them got serious prison time for what they did. The rest of the bad actors are still out there now, still doing what they were doing.Yeah, no thanks. I grew up around enough white trash to last a lifetime without watching it on tv. Unfortunately these kinds of people are common; the Jerry Springer Show is a good example of how many are out there. This description is all I need to decide to pass on watching: https://time.com/5807284/tiger-king-netflix-true-story/
Advice for the younger crowd, for the few bright enough to be here on DC: A good strategy for life is to recognize people like this from afar, keep distance, and not get sucked into their petty drama. Choose your circle of friends wisely. If it's your family there's no shame in escaping it and starting fresh on your own.
When in public around trash like this remember they don't think like you and me, they're manipulative, always looking out for themselves and willing to take from others, and are dangerous. Don't allow yourself to get bogged down with these people, you may regret it.
Of course anyone sharp enough to be here on DC probably knows this already.
I think the younger crowd watching it would take away the very lesson you suggest. Spot these kinds of people quickly and stay well away from them. The documentary is definitely a morality play. None of these folks come off looking anything but evil, which is why the main players have all complained publicly about the production. I think each of them thought the documentary would make them look good and their rivals look bad, but the camera was unflinching at showing them up for what they are.
