Just a perspective on kids entertainment
I think CGI has a lot to do with this:
Kids movies have gone into the realm of magic and fantasy more than problem solving. Marvel, DC, and YA adaptations all have this chosen one appeal which is fine.
Then, I think about some great movies for kids which didn't really do that:
1. The Sandlot
2. The Goonies
3. October Sky
4. Little Giants
5. Hocus Pocus
6. Sidekicks
7. The Rookie
8. House arrest
9. The Witches
10. It
11. Matinee
12. Holes
13. Radio Flyer
14. Monster Squad
15 Heavyweights
16. Stand By Me
There are some fantasy elements, but it tended focus on an ensemble trying to figure out a problem without having superpowers or this chose one aspect. It was more about banning together and working with their own strengths and weaknesses. Nothing against modern superhero flicks, but it almost seems like it would set kids up idols with superpowers rather than personality and problem solving.
I'm probably overthinking it.
