University of Tennessee English professor Richard Kelly recently published THE ANDY GRIFFITH SHOW. This book outlines why the show has been universally popular. Even in urban areas, ratings for the North Carolina-inspired show are high. Part of the appeal is Mayberry's Edenic quality and its resistance to change, giving the viewer a sense of timeless perfection. The relationship between Barney and Andy and how they complement each other also helps make the show a success.
