I started binge reading Asimov's books in that order as well and I share you sentiments. I guess that I liked the robot series more than Foundation since the characters were more relatable.

The Seldon Plan is both the protagonist and antagonist of the Foundation trilogy. The human characters are merely incidental. A masterful achievement.

I see the beginnings of something similar with The Flow in The Collapsing Empire.
