Saul has developed into a good show in it’s own right, just as Jake says in a very different way, yet much of its brilliance is borne from it connection to BB, the style and the genuine nature of the show.
For me it’s crazy to consider it better than BB as I think it owes any success it has to that show. By the third season of BB it had developed into groundbreaking television on par with anything else out there.
I love a slow burner but if Saul were to have came before Breaking Bad it would have been cancelled after season one or two. Greater concepts have been destroyed over less.
