This is an amazingly executed show. I'm quite impressed. When I saw the first episode, my impression was that it was OK, and I had the intention to watch the next episode.
After the second episode I was left with the impression that it was good, and I would watch the third.
The third episode left me enraptured, and longing to see the 4th.
I found myself going back and watching the first two episodes with a deeper introduction of the characters and very different perspective. I enjoyed the first two episodes immeasurably more, and picked up on subtleties I missed the first time through.
I'm genuinely excited to continue watching, and I know that as more is revealed about the characters, previous episodes will take on a different color.
