This spin-off from the TV series featuring the large purple felt dinosaur of awesome good nature is emetically wholesome. The screenplay doesn't stray much from the series' 'listen, sing, and rush off to the next thing' formula. The kids (disbeliever Cody, sister Abby, friend Marcella) and their bouncy uncle figure do it at Cody and Abby's grandparents' farmhouse, a Picture Post rural idyll rethought by Liberace. Barney can't be seen by the oldies, who respond with serene condescension to tales of his exploits. Numbers from the 'Old McDonald' song book feature a dog playing guitar riffs on his tail.
