Alien = toys = children
Spirited Away = toys = children
Rick and Morty = toys = children
What are you trying to argue here?
That mentally stable adults buy toys?
Or that corporations prey on adults with stunted growth to buy their products?
Does this look like something aimed at adults?

Just to clarify, there is nothing wrong with an adult watching a children's movie. There's nothing wrong with enjoying a children's movie. Many Disney animated films are classics for a reason.
What's wrong is when adults delude themselves into thinking that it's anything more than that.
The first half of Frozen is a good flick. Let It Go is a good song, performed by a very competent Broadway performer.
But if you start to argue that Let it Go is the pinnacle of adult culture, well, thats an issue. If you, as an adult, start to purchase Elsa pillows and Elsa napkins or whatever for your own use, that indicates that something is wrong.
