“Kids” in quotations because sometimes “kids” shows aren’t really just for children, judging by their nuanced jokes.
Could be old, could be new.
I like a lot, two that stand out lately are Star Wars: Skeleton Crew, and Star Trek: Prodigy.
Going back a ways, Reboot and Beast Wars. (Reboot, upon relatively recent revisit earlier this year, has a few jokes that I certainly wouldn’t have gotten as a kid nor even as a teen.)
You?
Not including my top show ever despite being too old for it, Franklin ( that preschool show ablutnthe turtle ), I’m going with Summer Camp Island as maybe 2nd place right now since I started rewatching it again. 6 seasons of a show starting off fairly episodic before coming together to tell what I consider a beautiful ending, even if it kinda feels like they had a network rush placed on them. Absolutely LOVE the final episode.
Though I have also been rewatching Code Lyoko since they have a full dedicated channel to the English dub of the show on yt. One of my all time favorite kids sci-fi TV shows period. Giant foreheaded minors attending a boarding school and fighting a virus capable of doing impossible tasks like making teddy bears turn into giant monsters or take control of rats to cause a plague or something along those lines? What’s not to love?
