Disney animation went through a really rough period during the 1960s and 1970s. Those were definitely the weakest flicks they ever made, probably everything after The Jungle Book (1967) through The Rescuers (1977), and many of those flicks (The Aristocats, Robin Hood too) were just rehashes with little creativity (Disney died in 1966). You can't really call it rotoscoping, but it's a lot more than similarities because it IS exactly the same choreography undoubtedly aided and abetted by non-human hand. It's a bit troubling to see Beauty and the Beast lift the dancing from Sleeping Beauty, but Sleeping Beauty lifted from Snow White and the Seven Dwarfs, so I can accept that easier, I guess.
