I really enjoyed the whole season. It's pretty par for the course to have the 'light vs dark' storyline, but it's rare to find it done in such a subtle personal way. The tiny details make this show, things they barely even draw attention to, but still have quite a substantial impact on the identity of the situation and the characters. Plus that 6 minute tracking shot in the biker episode was one of the best bits of cinema I've seen in a long time!
I've not read the entire thread so I'm sure someone has already mentioned this, but the Yellow King and Carcosa all have ties to a book written by Robert chambers. All the quotes we heard throughout the season "strange is the night when black stars rise, in Carcosa" "Take off your mask" are all taken from it. It seems odd that they didn;t address any of that in the last episode, so I'm wondering if that will be the through-line throughout the other seasons.
Also it's slightly cheesey, I know, but I did like how in the last shot, only 2 stars were initially visable with more and more coming into sight as the shot went on.
Anyway, bring on season 2!
