I’m older than that. I never made it through a full episode of any of the “action” shows; none of them ever showed me they had quality writing. Maybe it’s because they tried to play things serious so the 9-year-old boys would be terrified. They may have had their moments, but all I remember of them was bad dialog, minutes upon minutes of repurposed action animations as filler, and heavyhanded moralizing at the end. I also don’t remember my kid being interested in those shows, which I’m sure has a lot to do with it.
I do remember some cartoons he watched that worked hard to entertain the adults as well as the kids: Rocko’s Modern Life and Fairly Odd Parents come to mind; some shows were absolutely brilliant at appealing to both audiences.
