2 really was not utter dog shit. The worst part about it was the fact they didn't have a single director. Many shows wish they could have written a season 2 of TD, and I am a season 1 stan.
three was... meh. Felt too performative in the writing (returning to the tropes of s1 like multiple timelines and buddy cop) and reddit solved every twist. That's how formulaic and predictable it was. I watched maybe two episodes of s4.
