I may be off with this comment but they’re basically telling the same story as BB. The parallels between Walt and Jimmy are uncanny yet it doesn’t feel similar whatsoever, if that makes any sense.
There are parallels but not the same story. For starters, with BB, we did not know how it would going to end. With BCS, we know exactly how it would end, we just don't know the journey leading to it. The other fact is that with BB, the show was about change. It was watching the manifestation of someone who is an average American father transform himself into a violent notorious villain. Whereas with BCS, the show is about some people can never change even if they tried. Jimmy always been who he is. He always was Slippin' Jimmy or Saul lowkey. He always been a conman and a swindler. This is who he is the entire time, what is happening is Jimmy fully accepting who he is and not pretend to be who he is not.
