While the first two episodes were good, they still had the flavor of a "Breaking Bad spin off" to them. The third episode in this series completely sheds that crutch and stands on its feet very well. There is not an ounce of filler content.
We learn a little about Saul's criminal past. We see Saul begin to work his genius as the Kettleman plot thickens. And an old (or should I say new) friend has their first meaningful interaction with Saul. I really like the little musical pieces they do with the show about once per episode, and this one is no exception. The last 5-7 minutes were superb.
