While True Detective might not be a purely horror series, anyone who’s seen the magnificent first season of HBO’s dark crime thriller can attest that it contained more terrifying moments than many Hollywood horror films.

Starring Woody Harrelson and Matthew McConaughey, True Detective season 1 was a master class in atmosphere in tension, sporting a grimy, Seven-like vibe for much of the often gory and sleazy proceedings.

Then of course came season 2 of True Detective, which was pretty crappy. The show went away for a few years, but is now set to return to HBO for a third season, although it’s not clear when said new season will premiere.

Many horror fans were excited by the fact that True Detective season 3 had hired Jeremy Saulnier to direct the first three episodes. Saulnier directed Green Room, one of the most critically acclaimed horror efforts of 2016.

Unfortunately, Variety is reporting that Saulnier has left True Detective earlier than planned, only directing two episodes. This is said to be due to a scheduling conflict, and he’ll be replaced by veteran TV helmer Daniel Sackheim.

Sackheim is at least a qualified choice, as he’s directed episodes of top series like The X-Files, The Walking Dead, Better Call Saul, and HBO’s own The Leftovers. Still, it sucks that Saulnier had to leave, as anything he does is worth paying attention to.
