Nah. At least no more so than any other movie. “Adult Swim” is often VERY juvenile, but there are legitimate “grown-up” movies (I have to be careful not to call them “adult movies”) that are animated only to allow for representing things that until recently would be far too expensive to film.
If the adult circus comes to town kids will sneak in.
