Most children's shows from my childhood ('80s/'90s) were glorified toy commercials. Hardly any plot, every conflict was resolved by the end of the episode, and the status quo was always maintained. You could watch episodes in any order and you wouldn't miss out on anything important.
Not to mention, they had absolutely no standards for voice acting. Anyone could come in off the street and read lines and they'd put it in the show.
I was surprised when I watched children's shows today and found they had interesting plots and stories with real emotional stakes. Steven Universe, Avatar, Miraculous Ladybug, OK K.O., The Owl House, Samurai Jack, etc.
My wife and I started watching some children's shows with our young niece and nephew and we got so hooked, we went home and tracked them down to keep watching on our own! I wish I had shows like this when I was a kid.
