I'm disappointed but I was surprised that they even renewed it in the first place after the abysmal ratings, so this isn't a huge shock for me. The first season kind of lost momentum for me after a while, but I was still entertained enough to come back for another season. I hope Cannavale finds a new show to headline, he really deserves a hit. I guess I'll just have to depend on Westworld to fill my HBO void while Game of Thrones is in the offseason.
What would make me laugh is if it (very unlikely) got nominated for a bunch of Emmys after HBO preemptively pulled the plug.
