JazzG One thing I've found with my own kids is they don't really give a shit if the story is good, a bit of good action/comedy and their favourite characters is all they need!
That's for the normal kids … I was pretty picky as a kid, I liked things to feel like they were super-serious (bearing in mind I'm talking about what an 8 year old might consider to be super-serious!) and to be very aesthetically homogeneous, so I preferred the full-on epic fantasies à la Tolkien to the eclecticism of the portal fictions à la Lewis. I was also drawn to darker and more tragic material because it made me feel grown-up. Think I liked Arsenal as a kid in part because I knew the name was to do with guns and weapons. 😆
But even as kids I don't think any of us thought MotU was remotely serious. I had a mate at school who used to sing along to the theme song: I have the power / To pick up a flower / In twenty-fours or more … By the power of … Grayskull! We could tell it was kitsch nonsense.
We had better kids' stuff in the 80s than children seem to get nowadays, seems to me there were a few more joined-up serial television shows with proper dramatic arcs.
