Just finished it myself. It petered out quite disappointingly for a finish IMO. The last 2-3 episodes I just didnāt care anymore and had to struggle through just to get to the end. I thought around the middle third it was really good. Overall iād find it hard to recommend and could only give it a 6/10.
Started Counterpart last night and watched three episodes. TK Simmons is a master of his craft. He is ably assisted as it turns out but he makes anything he is in IMO.
Half way through the first episode and it looks very promising. Sounds like the type of thing @tassotti and @TheUlteriorMotive would have been involved in if they were around in the early 80s
