Star Wars a New Hope.
Batman, the animated series.
The Lord of the rings.
These are all regarded as some of the greatest fiction of all time. They are all written for adult adults and appropriate for children.
You can make things that engage adults without dropping every cuss word known to man, having perverted, gratuitous, sexual situations and horrific gory violence, and morally grey characters that celebrate evil like Deadpool. Itโs easier to put the filth in your work to get a shocking reaction, but writers with real skill can write for adults and keep it safe for kids without dumbing it down to a preschool level that would bore adults.
@heelvsbabyface I swear they don't know how to read or listen. How many times have you, Gary, MauLer etc explained this? And jeez I've written novels on here about why.
