Behind the Curve
The movie Mark and Patricia are watching around the middle of the movie is Dark City (1998), which is about a man who discovers he lives on a flat earth created by alien beings.,Featured in 420 AWARDS - 2nd Annual Event (2020),I have mixed feelings about his documentary. On the one hand, it is pretty clear that these folks are being presented as what they are - well meaning but maladjusted individuals who have bought into a down the rabbit hole idea with zero scientific support.

OTOH, it is also unfortunate to give exposure to such utterly bogus ideas. That is probably a disservice to the the rest of humanity.

As for me, I have been an amateur astronomer for over 30 years and can think of at least a half dozen simple tests that prove that the earth is indeed very round. Of course, presenting these to flat earthers would be a wast of time - if they cared about evidence, they would not be what they are.

In the end, the whole idea that such folks with such ideas even exist just made me sad.,
