I’m also not sure how you watch Better Call Saul without having seen Breaking Bad. It’s like watching Wicked having never seen The Wizard of Oz. Sure, you can do it, but a number of scenes, especially in the final season, don’t really make sense of you don’t know Saul’s story from Breaking Bad.
Plus, having watched Breaking Bad makes all the references/shoutouts in BCS even better.
