Netflix is obsessed
They are obsessed with fake documentaries about someone who did bad things yet, because some group of crazies says that person was misjudged, the "truth" is that they're "innocent" etc. Is Netflix just just bankrolling any project that says it's going to tell an "alternative" version of common knowledge of a crime? Or is someone with a lot of money buying their way to make all these? Or was there one show (maybe "Making a Murderer"?) that was so successful that it set the "winning formula"?
These things are barely a notch up from amateur conspiracy theory documentaries on YouTube.
