I mean, it doesn’t really matter if you don’t think toddlers need realistic depictions, if it’s running that means that toddlers are watching it or the parents of toddlers want realistic depictions.
What should they be watching? Superheroes? Other toddlers that behave like perfect angels? I’m sure there are enough other options out there, if they were watching those all the time then the realistic depictions wouldn’t be on air still. I remember watching Caillou and that was like 25 years ago, so obviously it’s probably doing something right.
It’s no different than spending thousands on travel or hundreds to watch movies at the theater. You’re paying for the experience and entertainment, not something physical.
