For the facts out of the way, it's only True Detective in last minute branding. It was supposed to be a one-off series ala Mare of Eastown called Night Country. It got Cloverfield'd and they spent some time rewriting and reshooting it to jam it full of S1 references.
Nick P, the writer/creator of TD, has been pretty much on full blast about hating it and not endorsing it. He's apparently an enormous ass and HBO refuses to work with him again, as well as 90% of the cast of the first three seasons agreeing with HBO on this, including the OG director Cary Joji Fukunaga, who knows why but he's effectively canceled from his own anthology.
All that said... it isn't very good TV. It reminds me of the podcast The White Vault /alot/ and seems to be taking beats and paths whereever it can to ape other cosmic horror. The Tsalal, for example, is a famous short story from Thomas Ligotti. They're very on the nose with all this shit in S4.
Since only from below can one better see the heights.
