Mesoamerican history nerd here, I could write 5-10+ page writeups per episode breaking down all of the historical and cultural influences and neat references in Onyx Equinox

Here's a 25 minute video on the first 3 episodes my friend helped with I also worked on to a lesser extent: https://www.youtube.com/watch?v=1Y2R3l94Hps

Also, I haven't watched the whole show, but "A Simpler Life: Ayohuih Nemilitzli" and "Showdown at the Mayahuel Gardens" episodes of Victor and Valentino are quite well done with how they use Aztec architecture (or modernized revivalist takes on it for the latter). I suspect that the staff on these, especially the latter, might have actually seen some posts that friend of mine did on Twitter, or my posts here on 4chan since they clearly used Scott and Stuart Gentling's paintings as a reference and the Gentling's art is hard to find outside of our posts.
