I'm two episodes into the current series and, well, let's say I'm undecided at this point. Some interesting characters, although they might have gone a bit OTT with the 'dysfunctional misfit cop' stock figure by having not one but three characters fitting this description. (I mean, one the reasons the first series worked so well was the synergy between the straight-man character of Marty, who despite his various neuroses and weaknesses is still ostensibly the all-American small-town cop with a wife and kids, and Rust, the traumatized, drug-damaged, Nietzsche/Ligotti-quoting loner mystic.)
Some of the dialogue is frankly ridiculous, although "I'm gonna buttfuck your father with your mother's headless corpse" had me convulsed with glee.
I'm kind of prepared for a letdown based on comments I've read here and elsewhere, although I've downloaded it now so I'm loathe to stop watching unless it actually just gets proper shit.
