The simple construction of good vs. evil: the good guys always prevail against all odds even if it makes no logical sense and the obstacles are not real obstacles, just mere discouragement, and the evil guy's motivation is just to oppose the good guys. Incredibly silly, and the selection of songs is tacky.
The Pearsons are less adorable and charming than they were in the first season, but you can still empathize and sympathize with them, and shed a tear or two when binge-watching every single episode.
