Except hunting, all entertainment is for kids.
Seriously, I'd agree that super hero films is a bit for children, but adults can enjoy things that are for kids. There's nothing wrong about that, unless you act in your life like a kid. That's another problem though. In this current generation, we've got many that never grow up.
God bless You.
