The ten-episode second season of Better Call Saul aired from the fall of 2015 to the spring of 2016. All the main cast members, including Bob Odenkirk, Rhea Seehorn, Patrick Fabian, Michael McKean, Jonathan Banks, and Michael Mando, return. Ed Begley Jr. has a multi-episode guest-starring arc this season, playing the head of the law firm Davis and Main, which was introduced in season 1. The series also continues to tie into the Breaking Bad universe by bringing back actors from the parent series, both small character actors you may not remember from Breaking Bad and those with larger roles. The main addition to the cast this season from Breaking Bad is Mark Margolis, who, of course, plays Hector Salamanca. The twins, Marco and Leonel, also appear, and Raymond Cruz reprises his role as Tuco. And, while Gus Fring does not appear in season two, there are easter eggs that hint at his arrival.
Interestingly, we see Hector when he can still walk and talk and get a glimpse at just how much of a villain he is. As was the case with the first season, the show uses a serial storytelling format in which the episodes build on each other. The season starts with another flash-forward showing Saul's mundane life in Nebraska as "Gene" but still pines for his life as Saul. Then, the series is primarily set in 2003 before the events of Breaking Bad as we continue to see Jimmy's transition into Saul as he pisses away every opportunity to be a legitimate lawyer because he cannot quite give up the life of the con man. We also see his relationship with Kim and his brother evolve, and we see Mike's transition from a guy who is not afraid to get his hands dirty but still has a code to what he would become in Breaking Bad.
The Blu-Ray set is a three-disc. It has a decent amount of extras spread across the three discs. Every episode has a commentary track that includes at least one of the showrunners, sometimes one or two members of the cast, the writer and/or director of the episode, or other crew members. The extras also include a gag reel, behind-the-scenes material, and a conversation between Mark Margolis and Jonathan Banks, which is very similar to the one on the Season 1 set between Odenkirk and McKean in which they discuss their careers and their characters on the show.
The series continues to be wonderfully written and acted. Even though it is set in the Breaking Bad universe, it has a much different feel than Breaking Bad, as it sets up what would come later. Even though you know that some characters are safe because they have to appear in Breaking Bad, it is still very suspenseful. There is definitely a Cain and Abel feel in the storyline with Jimmy and Chuck, and we see that Chuck has a large role in the creation of Saul Goodman. There is a lot of swearing and violence in the show, and there is a lot of swearing in the commentary tracks (including the use of the f-word). So, the show is not suitable for young kids or the easily offended. Ultimately, however, it is a great season and is absolutely worth watching.
