I think it was as good as it could have been given the start.
Looking back, I think had Frank and Paul not been in the show, it might have had a better flow. One the one end, you would have Ray and Bezzerides working the case from the Vinci vs. Ventura angle. You could have spent more time diving into these twins (maybe having them pair up with the two disgraced/setup police later in the season). Then, on the other end, focus more on the mayor's kid and Osip conspiring with Geldof, Chief Holloway and Burris on the corruption side. I think that would have made for a better story and we could have traded in Frank-Jordan Dr Phil sessions and Paul's PTSD/gay dilemma for deeper dives on the twins, the mayor's family and maybe some flashbacks to the robbery in 1992.
In the end, this show tried to do too much too fast and ended up spending way too much time on things that just didn't matter - while the main plot points flew by in the background.
