While the journey has been superbly executed, I am glad that Jimmy is finally Saul and that Mike is finally, er, Mike (not that their transformations are necessarily complete yet). I was a bit disappointed when Jimmy didn't break bad at the end of season one, but I've been as enthralled with the show as anyone over the past 4 years, so it ultimately turned out for the best. However, I do think that it was juuuuuuust slightly starting to feel like things were being stretched a bit. After 4 years I do feel like it's about time we got to see Saul in action (watching him build his brand, recruiting his henchman and secretary, working cases, etc). The Mike stuff was mostly excellent but I don't necessarily think it needed an entire season to play out - I would have liked some of that screen time given to Nacho, whom the writers keep toying with as a third main POV character before ultimately giving short shrift to every time (one of the drawbacks of having 10 episode seasons). I know they're playing the long game with him but his storylines have always been the weakest part of the series and it often feels like the writers don't know what to do with him but still need to keep him on the show because he was around during Breaking Bad.
Anyway, I thought the finale was great, with one caveat: the silly Terminator moment with Lalo. I don't like when either show indulges in comic book-y moments like that or the post-explosion necktie thing with Gus in BB.
