Yeah I nearly mentioned that - and you're quite right, that is what eventually keeps the show going, I hadn't thought about that but it is.
Coogler certainly has the horror and general directing chops for it, but it's really going to be on how well they can update the general concept to today, a world where everyone has a powerful videocamera in their pocket, and demented conspiracy theories are government policy (particularly relevant literally today, horrifyingly), rather than weird almost cool things some loner in his 50s believes.
