Idk, I feel like HBO (or any mainstream tele studio) might butcher it by trying to hamfistedly make it a revisionist Western along the lines of “White Man Bad” without catching the actual point about evil being inherent in everything. Thats undoubtedly a part of the reason as to why it hasn’t made it to screen yet - it’s not a story that fits nicely into the sort of Hollywood trope oriented storytelling that dominates mainstream TV.
Agreed. Its not even that a "white man bad" reading of Blood Meridian is wrong per se, its just woefully incomplete. It'd be like if Apocalypse Now was just John Wick in the jungle, or Blade Runner was just a police procedural with flying cars. Like, yes, that is the skeleton on which the piece is hung, but it is not at all what makes the piece great.
