Shut the front door! I had no idea Disney owned Spirited Away! I’m not super into anime (I probably would have been if I was born a bit later,) but I remember being a young adult, living on my own for the first time and having a bad flu. I happened to see Spirited Away while holed up in my apartment feeling miserable and it just blew me away.
Honestly if Disney is trying to appeal to older kids / tweens / teens in a gender neutral way, anime seems like an obvious route. In a way it seems like a perfect fit in terms of Disney’s evolution. A lot of programming for those age ranges appeals to kids by being crude, gross out, violent, etc. Anime often retains a kind of refined artistic quality yet is still considered cool with The Young People, at least many of them. Spirited Away would be a great choice but so would hiring some qualified anime storytellers and creating an original Disney anime film/s. I think a modern day Japanese princess making her way through Japan with some kind of mystical twist would be great. They could feature everything from Harajuku to picturesque Japanese temples.
