Spoilers if you haven't watched any of it.
I've watched it all and I'm in the last season, but it's just got too many flaws. Jimmy is just a turd/used car salesman/gutter lawyer, that's okay, but there's no character arc, there doesn't always have to be one, but he's just the sleaze he is in BB.
There's no chemistry between him and Kim, it's like they're cousins or just acquaintances, it just doesn't work as a believable couple on any level. The whole 'my brother's a genesis lawyer, but a nut' seems so fake it doesn't add any real value. He is so disappointed in Jimmy and then kills himself.
The worst part is it's so unnecessary. (A lot like Book of Fett) He's just not a worthy character in BB to have a back story, I think Mike's back story would have been potentially more engaging.
I'll stay to the end to see how it plays out, mainly to see how they get rid of Kim, but I couldn't watch it again.
Just my 2 cents.
I feel exactly the same way as you do. I thought there was--at most--a limited series to do with Saul and that's it. I don't believe for a moment Jimmy/Saul's relationship with Kim, I find Kim to be unevenly written and shallow; and much of the big problems for Jimmy are contrived and melodramatic just to push him to be "Saul." It reminds me of the clunky writing of
Joker, where the character has to hit milestones rather than evolve or change into what we're familiar with; a reactionary rather than a result or participant. Things happen
to him and he reacts in ways that are "Saul" and not "Jimmy
." Here's the same premise of same show minus all the fat: Jimmy McGill is a good but greedy public defender, and hustles on the side, loses his license, moves to New Mexico as Saul Goodman and hustles as a criminal lawyer. Done.
Saul is a dirt-bag, an irredeemable and unapologetic dirt-bag, and that's what made him fun in BB. The fact that there's now 6 seasons of what is ostensibly filler detailing
how he becomes a dirt-bag is so utterly boring and contrived that I finally lost all interest when they brought up a plot point they resolved from season 2 (Jimmy v Hamlin) as a stinger for the final season.
Better Call Saul has its moments but is it just me or does this show feel like the worst of BB? The filler episodes in the latter end of the series, the dull and melodramatic first two seasons of BB, all combine into making something that makes the show feel like a relic from a bygone time. The show's structure makes it feel so old since Breaking Bad aired, and TV has taken some real changes to it. These kinds of long-running shows are really over due to all the streaming services available, it's shaped how TV is consumed (I hate using that word) and it's pushed American television more towards the European style with short, limited-episode stories where concision is the name of the game: get in and get out.
I did earnestly watch this series at first but that was when it first aired and I still had cable, but as more and more reasons came up to delay each season's production, I eventually forgot all about the series and got rid of cable all together. I only remembered it when it came to Netflix and caught up there. I likely won't be following up after.
