This is the origin story of a character who is far from a superhero, but still enjoyed a position of power in the Breaking Bad universe. Saul Goodman was the guy who knew how to get things done, and his knowledge in money laundering and survival were instrumental in Heisenberg’s career. This show explains how a broken down man named James McGill became that fast-talking TV lawyer.
What made the first episode so great was how Saul was portrayed as someone who had very little, but found ways to get things done.
If Breaking Bad was a show that often reveled in showing the viewer surreal amounts of money, Better Call Saul takes the opposite tack and rubs our faces in McGill’s universe of barely running cars and prosaic environments.
