Finished this and loved the hell out if. Sure it had elements of a lot of genre work but it did it all so well. I think this is Kinnaman's best screen work to date. The obvious influence in this season's story was the hard boiled film noir detective and I think he pulled it off magnificently, because he infused the character with great humanity, intelligence and charm while still being a man haunted and shattered internally. Will Jun-Leel also matched him as the original Kovacs. The cast around them was also top and I never felt a false note from any of the performances myself.
Production design, dialog, all tops. I will echo to a lesser degree than some that yes, there were quite a few times that I felt they didn't make many aspects of this universe as clear as they could. On the other hand it's a mystery, no? So information is gonna tend to be doled out piecemeal. Also, there are, besides the clear intention of what path we leave our main character going down at the end of the season, lots of threads and hints of story elements that will get more fleshed out in future installments, which I suspect would lead to a more "cosmic" storyline or arc.
This was in my opinion one of the best Science Fiction shows I have seen in a long time. I hope it was not just a one off and it comes back for a second season.
