An enjoyable, straightforward take on a radically unscientific community that has completely dismissed reality and essentially become a kind of antiscientific cult. It's an easy and fun watch, if also a dispiriting one. The filmakers stress the image of flat earthers as being in the movement because of the community (Mark Sargent is a charismatic, innocent deceiver) and spend a fair amount of time on the "scientific" members who are trying to develop a test that will prove reality is…
More interesting to me as an artifact than an actual entertainment, but it retains a lot of it's power. The forms of it -the bad acid trip, the motorcycling scenes, the wandering around the hippie commune- retain all of their oddness and outsiderness in the modern age.
