Oh yeah, I see it wasn't specifically about animated shows / cartoons (sort of misread that).
My 12 year old liked Pixar stuff when she was much younger (like 7-8 or younger), never was into any Disney traditional type animation - and now, loves anime which is 95% of her "serial watching", we did watch Gravity Falls and Adventure Time together

Otherwise it's lots of short form video - she rarely watches a feature length movie, she watches a lot of "how to" on YT, etc., for cosplay designs, art. Now she's been really engaged in learning some 3D type art and design for video game characters.
I don't think there's anything particularly wrong with watching someone else play video games, hahahaha, other than it seems sort of silly

I mean, like all content, it needs to be monitored, occasionally screened, etc.
