All I can say is wow. What. A. Show. Lives up to Breaking Bad 100%, honestly it's probably even slightly better.
And the characters throughout the show, and Saul's character "development," it's perfect. I would never have guessed the ending. I'm so sad I'll never get to watch it for the first time again.
The best part of the show for me was simply having Mike be such a prominent character. I did not expect their to be very many "returning" characters from Breaking Bad, but when Mike became such a main character of the show I was ecstatic. Really makes me see him so much better than I already did, and he was already my favorite character from Breaking Bad. Also Fring's death stare is perfect as always, albeit I wish we saw him just a lil' bit more.
