The show is amazing, as you said season 1 had amazing characters and it was really enjoyable to watch. But the thing is with season 1 it felt like it dragged way too long. As for season 2 it was more fast paced, but everyone was so used to the original cast that it kinda pulled them back a bit in my opinion, but the fight scenes of season 2 were CRAZY good. And finally the animated movie of Altered Carbon felt clunky in fight scenes and realism, but it was still not that bad to watch (once)
