I'm a Dane, and grew up with Danish children's television, including the shows mentioned in the article. I just recently re-watched one of my favorite shows "Nanna", which you can now stream from the archives of DR. Even as an adult, I still enjoy watching it for its humor and creativity, and for the fact that it doesn't speak down to its audience. I don't think that can be said about most other children's shows.

Nanna: "What're you doing?"
Mother: "We're having sex, what're you doing?"
