I and especially my sister grew up on Sesame Street, Mister Rogers, and a near endless supply of low-key foreign animation shown through that primordial Nickelodeon show, Pinwheel. (The Magic Roundabout, Paddington Bear, that sort of thing.) The difference in quality between children's programming then and more recently was such that when my nephew was little, my sister outright banned him from watching certain "age-appropriate" shows and even entire networks like Nickelodeon.
It's refreshing to see shows like Bluey that are thoroughly modern, but produced with old-school values: respect kids' intelligence, show positive role models, be realistic about feelings and conflict, and keep everything low-key and don't amp the kids up.
