After two episodes story looks very much like a Hollywood take on venerable Polish classic "Seksmisja".
Underground world working as a metaphor for a totalitarian regime.
So far, it nicely explores the topic of how repressed citizens subconsciously support the regime. This constant schism between awareness they are lied to and clinching desperately to rationalizations provided by the regime.
(Spoiler warning)
This is brilliantly depicted in the scene where Sheriff verbally believes "the vaccine pill" explanation against all his knowledge and against his wife.
The discomfort of accepting the truth is too much of a price. The consequences are dire.
Very timely served food for thought at a time we are facing a war initiated by Russian regime..
