There is still the same period/political drama wrapped around the zombie plague but the drama is spread out more across the episodes and doesn't bog down the pace to the point of being slow.
I would say that the political drama adds to the suspense and intrigue of the whole story now.
While the movie Rampant was part fast paced actioner, Kingdom isn't quite in the same style. There is still plenty of action but the show also retains tense atmosphere in parts that will have you gripped.
Its such a shame the first season was only 6 episodes long. I wanted much more and such a cliff-hanger of an ending
