The first two episodes jump around a lot and don't really lay out details in a way anything like a normal documentary would. This appears to be because the are intentionally letting Q people themselves lay out the story, which is a smart way to avoid death threats but is reliant on the narratives of people with disjointed and irrational thinking. They succeed in establishing that there are lot of the core Q people that are outright nut jobs and often of seriously compromised intellectual capacity and judgement.
It gives the impression we are witnessing the birth of a new religious cult along a similar line to scientology, but potentially much bigger. Even when the 'facts' underlying their beliefs are being torn apart the Q believers are capable of of some pretty impressive mental gymnastics to avoid acknowledging they have been sucked into a cult.
Episode 3 opens up the fascinating and key subject of the Luther Blissett group and the novel "Q" first published in Italian in 1999 which is obviously the origin and template for Q'Anon and makes the whole story take an L'ron Hubbard twist.
