I am really going to miss this show. A fitting ending as Jimmy redeems himself.
You have to give the writers and the actors a huge amount of credit. Every character in this was engaging.
Throughout this last season, I have gotten lost a couple of times. There were scenes I didn't understand and conversations on this board I understood even less. The reason for this is, I have yet to see a single episode of Breaking Bad. I find it hard to believe it could be better than Saul.
As far as I can see, not knowing the Breaking Bad story/characters didn't detract from Saul. Maybe you don't miss, what you don't know.
