It's been noted on this forum how a majority of Disney's animated (and live action) movies are either retellings of old fairy tales, or adaptations from obscure, yet well-loved books. Likewise, it's also been noted on this forum how Sid & Marty Krofft often rehashed the exact same premise for many of their old Saturday Morning shows: strangers in strange lands trying to get back home.
It's just now occured to me that Hanna-Barbera was a tad notorious for this as well with many of their properties. In some cases, you have animal protagonists who are always in the crosshairs of human antagonists - whether it's Yogi Bear and Ranger Smith, Penry/Hong Kong Phooey and Sergeant Flint, the Hair Bear Bunch and the zookeepers, or whatever else there. Then, you've got something they became notorious for in the 70s, which was basically rehashing the concept of Scooby-Doo over and over again, with a gang of groovy late teens/young adults, and their talking animal companion, who solve kooky mysteries.
