Year after year, people keep ushering out new movies, books, miniseries, and special episodes of shit like Dateline in order to dig this up like a time capsule full of half-assed theories and random speculation, because isn't this story great? At this point, there's an entire industry of filmmakers who could probably retire thanks to the death of a six-year-old. It's the best thing that ever happened to them.
If that sounds pessimistic, you have to take into account the fact that there is no new evidence. Each new movie or miniseries isn't providing new insight; it's taking old shit and old opinions and trying to mold a pile of turds into a chocolate mousse. Just last year, CBS rolled out a circus sideshow of a documentary which concluded that the brother killed her.
They reached this conclusion in much the same way you do when playing Clue: They just picked a guy and guessed. They literally had no new evidence; they just felt like giving slander a try in a bid for ratings.
The whole JonBenet cottage industry is a lot like the movie version of Clue, now that I think about it. We have the details of a crime, now let's just run through a bunch of alternate endings in which it's more or less plausible that each new person we accuse did it, and that'll be super entertaining. The 2017 documentary which will air on Netflix is described as a "vision of a mythic American tragedy." But it's not a mythic American tragedy. It's the personal tragedy of a family who have to keep living through it 20 years later. Imagine if your child was killed, and for 20 goddamn years, no one would stop talking about it ... or accusing you of doing it, despite the fact that you'd been eliminated as a suspect by the district attorney. How do you manage to keep going through your days with this shit tossed in your face endlessly?
