Re-watching the series (I ain't got #### else to do). The show is so impressive for so many reasons, but their ability to adapt and the risks they've taken in doing so are really amazing.
It seems clear that dawdling on Slipping Jimmy/Chuck/Kim was not the intent. I'd guess a lot of Season 5 was probably originally planned for somewhere around Season 3. But they adjusted, and didn't give the fans what most would have originally wanted (many seasons full blown Saul), and brought them to an even better place as a result.
Such a huge risk that paid off. It fits in with their tendency delay gratification for a deeper impact. Sort of the like Kim montage to find Mesa Verde to get out of the cornfield. It felt a little long in the moment, but it led to a much deeper impact when Howard crushed her dreams under that HHM flag.
I'd love to have roughly 20 seasons of Saul/Kim/Mike dealing with the cartel together, but they took the journey here that will make these next 11 episodes have the maximum impact.
