Just finished watching it; I was glued to the seat the entire time and ended up watching the whole show in two sittings today. I really enjoyed the tone of the series. Was it particularly deep? No. Was it the most original idea to grace television? Certainly not.
It was, however, extremely well-executed due to its consistent and strong vision, very adherent in maintaining its tone and atmosphere (which I felt was phenomenally engrossing), knew its limitations and constraints and used them wisely (in particular knowing that most of the side characters were quite shallow, the story was pulpy, the visual affects, and the self-awareness that it was very much like an extended King/Carpenter/Spielberg), and had some great performances. This is definitely my favourite Netflix fictional production so far; it really felt like an extended movie to me and made the best use of the medium of any of their productions to date.
