To grab an analogy from a different fleshed-out universe, it's quickly becoming the case that Better Call Saul is to Breaking Bad what Rogue One is to the original Star Wars trilogy. Tonally, it’s not the same thing, and it’s not trying to be. It’s subdued and small-scale instead of boisterous and universe-spanning. The lighstaber-duel-style action set pieces are deliberately absent. Hell, you even know how it’s going to end.
But just as seeing old favorites like Darth Vader, Princess Leia, Mon Mothma, and Grand Moff Tarkin in a new and unusual context managed to provide a familiar thrill without feeling like a retread, so does watching friends and foes from Vince Gilligan’s meth masterpiece pop up on BCS. It’s familiar, yes, but the familiarity serves, somewhat counterintuitively, to keep the show fresh and distinct.
