I actually liked a lot of season 2, but I did not like the direction they went in. Several HBO shows have this problem where they spend so much time world building and character developing and mystery building and then they go “crap we need to move the plot a whole bunch” and throw together the final 2 episodes. I know that the Killing got a ton of crap for going the other direction and making it 2 seasons, but it happened on GOT, it happened on True Detective, it happened for WW.
I loved the Young Pope / The New Pope so much that I will excuse their good, but not great final two episodes as well which suffered a bit from this as well.
