The above condition affects spinoffs of movies that are ultimately preferable to the source - "Mighty Ducks," in this case, accomplished it by bearing as little similarity to the original as possible. Originally "The Bad News Bears" on ice, the cartoon revolved around a group of hockey-playing mallards from another planet who arrived on Earth, and with the loss of their leader wanted to return to Puckworld - but in the meantime they became a wildly successful ice hockey team. (The Disney folks sponsored a real-life team of the same name, explaining the credit for the National Hockey League. The appellation "The Coolest Game On Earth" is harder to justify...)
Unlike the other poster, I don't really think this had the right stuff to be up there with "Gargoyles" - it was more light-hearted on the whole and not really too layered. But it was fast and pretty entertaining, if not the kind of thing that could last too long. The House of Mouse has done better ("Gargoyles," "DuckTales," "Kim Possible") but they've also done worse ("Buzz Lightyear of Star Command," "The New Adventures of Winnie the Pooh," "Chip'n'Dale Rescue Rangers").
"Ducks ROCK!"
