I've kept the same opinion about Season 2 ever since the 6th episode. Season 1 was so amazing, Pizzalatto spent like 10 years writing it I think. Then in less than a year he had to crank out an entirely new story that was on the same level as Season 1. I spent the first 6 episodes of Season 2 waiting for it to reach those epic levels of the first season until i finally realized it was just never going to happen. On its own, Season 2 was not bad, even pretty good at times. But following up Season 1, and for it not to bring the same intensity and quality, it didn't stand a chance.
Individually I thought all the main actors did a great job, the show just had a real tough time coming together as a whole and I think you blame the writing/directing on that.
It's been a couple of years now so I have a little more faith that Pizzolatto makes sure Season 3 will be better. I've liked Mahershala Ali ever since he was in "Benjamin Button" and the director Saulnier is a little unknown to me but I thought "Green Room" was pretty cool.
