Not yet, but I am sure I will want to do another BB re-watch at some point.
I will say, though, and we might have touched on this already, that I disagree with the sentiment I have seen since the BCS finale that we know now how much Saul meant to Walt. That is not new. It was blatantly obvious to BB viewers to Saul had a MASSIVE hand in Walter White building his meth empire, but I think the BCS finale was Jimmy McGill letting the (imaginary BB/BCS) world know that, "hey, Walter White is not a name any of you would know without ME."
I suspect some could re-watch some of Saul's more relaxed BB moments and relate them to Kim in some way. For as much as a clown show as Saul could be when he was doing his thing, he could do the more subdued moments really well as well where you saw a slightly different side of him, a side that was obviously fleshed out in BCS. Like, you could tell Saul didn't feel great about the ruse where he had to have Francesca call Hank to tell him Marie was in the hospital (to get Hank away from the RV where Walt and Jesse were trapped inside).
I always liked the moment late in Season 3 of BB when Mike threatens to break Saul's legs if he doesn't tell him where Jesse is. When Saul breaks and tells him where the notepad is where Jesse's (fake) location is written, he still tells him not to touch anything on his desk. While not a tough guy, Saul still showed some balls there by giving that directive, and one could definitely now see that as more impactful now having seen the backstory of how their working relationship began.
