"Like its predecessor Breaking Bad, this is a series you can’t just half-watch while scrolling your phone, because if you do, you won’t know what’s going on," says Matt Zoller Seitz. "The show can be hard to follow even if you’re watching closely, because so much of the plot is inferred." He adds that "more so than most current series, the pleasures of Better Call Saul are almost entirely visceral and emotional. It’s about what happens in the frame: what you see, what you hear, the looks on people’s faces, and the thoughts that pass through their eyes as they contemplate their next move. Series creators Peter Gould and Vince Gilligan were smart to rethink the tone of this tale as they refocused the Breaking Bad lens on Saul Goodman, a.k.a. Jimmy McGill."
