Documentary films, as well as documentary series like Making a Murderer have proven successful for Netflix, and most other streaming services, with the exception of Disney+ I guess, have joined the trend with their own options covering true crime events, serial killers, and whatever other twisted parts of the human condition might entice viewers. If nothing else this sort of production usually gives the story closure as the guilty party is usually known. Unlike something like Unsolved Mysteries, which by its very nature gives us stories that are missing resolution.
