I find this show extremely interesting but likely not for the reason most other people who liked it do. I think this is an interesting look into the motivations and mindset behind adults who never learn to think critically and lack a firm scientific education. These people constantly buy into misinformation and legend and come up with some truly wacky ideas. The dowsing rods, the paranoia, the confirmation bias, the pareidolia. It truly is an interesting insight into the minds of people who are delusional but not the point of being a danger to society or being classified as 'mentally ill'. A sort of 'monomania' as they would have said in the 1800s. How much does anyone want to bet that these guys are all conservative?
Unlike others, I don't believe this is contrived or fake. I think these guys truly do believe what they're saying and they are full of conviction for their cause. The problem is that they lack critical thinking skills.
