I've spent the past few days thinking about this finale. A beautiful and poignant ending that not only stuck the landing, but elevated the entire series in my eyes.
Odenkirk did his best acting on the show (and of his career, of course), shifting personas from the weaselly Saul Goodman to vulnerable and introspective Jimmy McGill, while still making his personalities feel like the distinct sides of the same human being. He was beautifully played off of as always by the moving Rhea Seehorn, whose silent facial acting in the courtroom scene I'd say was even better than her performance in Waterworks. I don't know that I'd say I have a preference between this and its predecessor (which I'll need to fully rewatch) but this finale cemented Better Call Saul as a show that, even if never quite as addictive as the pulp entertainment of Breaking Bad, was the more thoughtful and challenging drama.
