Here's a decent blurb but it doesn't get into the strange and subtle elements that I'm highlighting.

It's on Amazon Prime if you're interested.

Anyway, there is subtle mockery of crazy conspiracy theorists predicting the "inversion" [end of the world] and they show a torsion coil (rodin coil) model of the universe - which is a very deep rabbit hole if you're into forbidden math and physics. Also there is mockery of Christianity of course, but with an interesting endorsement edge too.

Its interesting to me when something like that gets introduced to the world in such a dismissive and mocking way - almost makes it worthy of deeper research.

There are also more dark and disturbing elements but I'll let you notice those on your own.

This write up gets into the esoteric. https://fantasymerchant.com/2020/11/10/prophet-of-the-second-inversion-busters-mal-heart-review/
