The missus and I finished the second (and last) season last night and it was great. I guess I am a fan of alternative Universes, but I have to say this one was well done and specially very well acted. Seriously, J. K. Simmons does such a fantastic job, I bought the premise about a minute into the reveal. It is Cold War writ if not large at least bi-universal.
If you are bored and need to watch 20 episodes of good script and great acting, this is available in Amazon Prime Video and I guess in Starz on demand.
