It definitely isn’t. I’ve never really got people saying that. And no one really does in the wider cultural landscape. It’s more of an “acshully guys” opinion… and I can sort of understand it in isolation. It is after all a largely much better made show, considering it’s produced by exactly the same people, all operating at a higher game than they were at the start of BB, and with more nuanced writing, but it also doesn’t really have any dynamic urgency about its storytelling on the whole..
BB, for example, had 5 very distinct seasons where you could not just point to the different arcs and tone of each one, but to the progression of each of the characters, whereas watching BCS is more like stewing in that world for a bit. Each season is kind of the same (at least until the last one) and Jimmy/Saul is relatively the same character throughout. You could’ve ended it after season 1 and it wouldn’t seem weird that Saul in BB was how he was. If anything the changes (which have been good outside of that context) have only made it weirder, as he’s mostly just flit between 70% Saul and 90% Saul at different points up until now, and even Kim’s descent only really kicks in S4 (it’s really about her, or his affect on her, if you’re looking for progression)
You got the Chuck stuff at the beginning and the Lalo stuff at the end to give it some identity and personality but it’s rather meandering by design. I can’t really remember what happened in the middle, and couldn’t point to “that moment in S2 or S3” for example as something to signpost it’s highlights. It does all build to a good final season crescendo, but a lot of it before then feels like a Breaking Bad VR experience at times.
Though weirdly unlike a lot of people I kinda like the weird stuff they’re doing at the end. It helps give it something to distinguish it. It’s bold, even if it’s a bit odd and slow so far (the show is slow. You’ve just gotta get over that. it is what it is.) Which was actually my only real gripe with how BB ended - that it was a relatively conventional finale for all the mad shit that happened before.
BCS is still a great show, but only an all time great on a mostly technical level.
It would be interesting to see if anyone watched this without seeing BB, and whether this last stretch makes any sense at all…
