It is a very general movement, not only in animation. Youth, popularity, fame, and pleasure are what is good now when it used to mostly be characteristic of the bad guys.
I don't know the reason behind it all, why popularity is good, why being yourself is bad and only gets you into trouble. It is a shame, how culture seems to change for bad lately.
Of course like us there will come a time when we learn to think for ourselves and decide what is right and what is not and how we think we should live our lives. We can only hope that the next generation of children will be able to do the same.
