What Disney really is searching for is a "Mermaid - Lion King" run...
Pixar extended that with Toy Story, but wrong demographic...and wrong style. The animated musical (the music is part of what kids get addicted to, and something lacking from Pixar releases, etc...)
My point is...a whole generation grew up singing songs from Disney movies...then in the late 90s, they hit jackpot, and a whole new generation grew up also singing songs from Disney movies.
They seek this, and need it, as now those of us who grew up during the second age, our kids are reaching the age of not-believing...and they need to do something quick. Fast blast high profit action films like Pirates will work, forgettable ones like Oz will also make money, for nostalgia...
But, until they find new stories to tell with a Menkin / Rice or Sherman Brothers level composition team again, and recruit them to turn great animated films into animated musicals...they will be lacking. And, their brand will suffer in the long run. As will Pixar.
Just my opinion.
Rapunzel was probably the closest they've been to this dynamic in a very long time.
