It's time to get all caught up on Better Call Saul ahead of the premiere of the show's penultimate season, as season 4 of the Breaking Bad spin-off is now streaming on Netflix. Previously, the first three seasons had been streaming on the service for quite a while, leaving those without AMC who rely on Netflix to watch the show clamoring for season 4. That day has finally arrived as all four seasons of Better Call Saul are now available to watch on the streaming service, and if you're watching it for the first time, buckle in because it's the craziest season yet.

Bob Odenkirk leads Better Call Saul as aspiring lawyer Jimmy McGill, who one day becomes the "criminal lawyer" we all know from Breaking Bad as Saul Goodman. Co-starring on the series is Michael McKean as his older brother, Chuck, an experienced attorney with an apparent allergy to electricity who's constantly clashing with this younger sibling. Also starring on the series as original characters new to the franchise are Rhea Seehorn as Jimmy's girlfriend and fellow attorney Kim Wexler, Patrick Fabian as competing lawyer Howard Hamlin, and Michael Mando as local gangster Nacho Varga.

Season 3 of Better Call Saul, which is also available on Netflix leaves off with Jimmy and Chuck having an ultimate falling out following their dramatic showdown in court. I won't get into what happens in season 4 here, so as to avoid spoilers for those of you yet to watch it. What I'll tease here is that you can expect to see even more familiar faces from Breaking Bad appearing along with several Easter eggs and other tie-ins, making the spin-off feel closer in tone more so than ever to the original series. We might technically be in the past before Breaking Bad begins, but the tone of Saul season 4 really makes it feel like you're watching the same series.

Many Breaking Bad characters have already been regularly featured on Better Call Saul, most notably including Jonathan Banks as hitman Mike Ehrmantraut and Giancarlo Esposito as criminal mastermind Gus Fring. Some other notable guest appearances include Laura Fraser as Lydia Rodarte-Quayle, Mark Margolis as Hector Salamanca, Max Arciniega as Krazy-8, and Lavell Crawford as Saul's associate Huell Babineaux. Also confirmed to appear in the upcoming season 5 are Dean Norris and Steven Michael Quezada as DEA agents Hank Schrader and Steven Gomez, respectively. Bryan Cranston and Aaron Paul still have yet to appear on the series as Walter White and Jesse Pinkman, but it seems probable to happen before the series conclusion.

For better or for worse, AMC has also renewed Better Call Saul for a sixth and final season to premiere in 2021. The end might now be in sight, but bringing the show to a close while it's still amazing rather than dragging it out until the quality drops is probably the right thing to do. It would appear the creators have learned something from Breaking Bad. You can watch the season 5 premiere when it premieres on AMC on Feb. 23 and the first four seasons of the show are now streaming on Netflix.
