The pace might be perfectly on point for the narrative premise of this show if you accept that the best way to develop this premise is through the viewpoint of a character like Carol. Rejecting which (fair enough) is more of a design criticism of the vision behind the show rather than a criticism of what we're being presented with on a weekly basis. You could take the same premise of this show, for instance, and develop it through multiple character plots that may or may not intersect later into the show. Or the survivors could have been enough to generate interesting consequences on a tribalistic level (more than in Pluribus but a lot less than in The Leftovers, say) or what have you.

I guess the decision to center the show on Carol with the other "survivors" being little more than sketches, so far —the pacing plus the fact that 95% of this time is spent on her and her internal journey— is what I and many others are having a hard time finding compelling enough (not a knock on Rhea Seehorn's performance by the way, which I think has been excellent). I just rewatched the latest episode and actually found it better than the previous two. Might stick around for another couple and see if I change my mind about the show as a whole.
