I seems to me that the author actually enjoyed the shows and I mostly agree with his assessment, but he can't have been watching too much because he missed some important shows that are in fact educational.
Most prominent of the educational shows is Mr. Beard, who teaches numbers, counting, simple math, letters and simple spelling. The show is weird and quirky, but also features some great songs. The whole thing is backed by some pretty great apps, which expand on the educational stuff.
There's also a great show about kids helping animals in trouble. They don't pretend that the kids do most of the work, it's a professional that does the heavy lifting, but the kids get involved as much as possible.
I don't mind watching these shows with my kids, but I'll leave as soon as Dora or Thomas the tank engine or Chuggington starts.
If you're interested in watching some completely outrageous danish childrens TV, go watch "Carsten og Gittes vennevilla". It's created by the duo "Wulf Morgenthaler", who have produced some the weirdest stuff on danish TV. Particularly the one where Carsten creates a fox is a hoot.
