I do so indiscriminately: as in, I watch whatever appeals to me, so I don't think too much about whether something is for 'kids' or 'adults.' If I find it entertaining and it checks my personal boxes for good storytelling, humor, animation, etc, then I'll watch it. When I was 19, 20-ish I went through a phase where I watched the entirety of what was available on YT for free of 'The Moomins' program from the 90's (suddenly it became quite popular last year and now is very easy to find all episodes apparently haha). This past year I've even watched some of 'My Little Pony, Friendship is Magic' for no other reason than I find it mildly entertaining and enjoyable to watch, especially in the background as I'm working on things. My thing is, I'm really particular about TV, and won't just watch a show for absolutely no reason. More than anything I re-watch my favorite things over and over, since I know I love them if I bothered watching them in the first place.
I also find that so-called kid's TV (and media and literature in general) is often not bogged down by desperate attempts to be gritty, shocking, etc. that so much adult programming is. I'm not really squeamish or touchy about sex and violence and so on, but there's a difference for me in that being handled well and relevant to the show, rather than done again and again and over-the-top because that's what grown-ups like, right?
I couldn't leave off without mentioning one of my favorite shows of all-time, 'Batman: The Animated Series"
While I like Batman content (films, comics, shows) in general, I personally prefer when it doesn't take the uber grim-dark route, trying to be edgy at the cost of genuine character development or good story. I *love* BTAS for multiple reasons, only one of which is that it's excellent Batman content that gives not only Bruce Wayne-focused character depth, but explores villains and side-characters well too; all of this without having ultra-violence/sex/etc. Again, not that those things are inherently bad, but I like when good stories/writing can stand on their own 2 legs rather than needing to impress an audience that demands edginess.
