I just watched it and I gotta say it was pretty ok, maybe even good.
It's pacing is far more "TV" than Season 1 which feels like an 8 part film, and I was definitely bored through the middle 4 episodes, but overall I think it did have something to say that was well communicated.
Definitely pretty bleak though.
I've only watched seasons 1 and 4. Most people say season 2 is not good, and season 3 is better, but I have a friend I trust wrt thinking about media who says season 2 is better than 3.
