This show seems to be a really frustrating mix of highs and lows. I did watch the first season and it was well done and interesting. The 2nd season got some mixed reviews early on, so I didn't prioritize it. Fast forward thru the pandemic etc., and it gets canceled by surprise with what I heard was a bit of a cliffhanger that the producers thought they would be able to resolve in a final season. I'm not surprised (unfortunately) when it happens on Netflix or Amazon streaming as they throw a lot of darts at the wall but HBO is usually better about that.
