That seems more like a message for parents to think makes for a good kids movie message - whether kids glom onto that is a different matter.
A Bug's Life has a great message around trade unions and organising (ironic for a Disney product) - do kids get that, or just laugh at the burly bloke ladybeetle?
Does he, or are we just seeing it through the kids eyes?
Yeah, I do this. It doesn't always work. I'm looking at you Birdman.
Does that critique still fly two decades into the Pixar age? Toy Story works (for kids and 30-somethings) for the most part, as do the first two Shrek films, among others.
It probably is - I find Iron Man a better series because they are more self-contained - Cap one is a bit of a bore (I'll very likely never watch it again), and two and three are so intertwined in the broader Marvel story that they don't really feel like Cap films to me.
