It’s obvious that the main characters being cavemen from an advertising campaign was the only selling point for this, never mind the need to hire good writers to make the show work. And shoving social issues down the throat of the audience is something that even a serious hour-long series gets hated for.

I wonder, have you ever seen the California Raisins cartoon? It was on CBS Saturday Morning back around 1988.
