This season has very much been centered on their dynamic, even the particulars of the plot has more and more has to do with the Cartel stuff.

They definitely wasted four episodes of Mike, and I'd still like to see more Nacho, but I think they're setting things up for the last three episodes to be interesting on that front.

I think that the problem is with this season is we really do know how most of this turns out. Like, even more than most seasons. Lalo doesn't drive Gus out of business. Mike becomes and stays the top guy in the Fring organization. The only "mysteries" is why Kim isn't around and what happens to Nacho and his father. And I feel like after what happened with Mike last season, the arc can't that he lets both of them die.
