Yet what unites this season most with the other two seasons of True Detective is an overriding thematic concern that influences all of Pizzolatto’s work: America is crumbling, and its institutions are barely enough to hold the darkness at bay. The world is full of evil, and all that can stop that evil are the actions of the handful of good men left to stand in the breach.
Season three is both the most mature exploration of this theme — in that it constantly pokes and prods at that idea to find holes in it (a Milch specialty), but also in that it makes ever more clear that whatever good America used to stand for, it’s since been subsumed by far darker portents.
This is where True Detective’s Lovecraftian overtones most come into play. In season three, the world is full of horrific religions and cults, just waiting to abuse and exploit the innocent — but that’s not so very different from the ways our institutions and other cherished organizations, ones meant to protect or edify us, stand idly by and let that abuse and exploitation happen. There are still good people within these institutions, but the overall effect is like the implacable Old Ones of H.P. Lovecraft’s horror fiction, who cared little for human beings and simply wanted to be fed a constant string of appeasing sacrifices.
