I well remember the extreme anti-Blyton-ism.
At the time I got the impression that it was largely because so many of the books (esp. the FF) were about very obviously middle class children.
As a former FF fan, I thought it very unfairly prejudiced.
As for Noddy and Big Ears, well, clearly old Big Ears was Up To No Good, befriending a new little Noddy-person like that!
I should imagine that EB has been responsible over the years for getting masses of children into reading, so good on her. As an ex librarian I always felt that it didn’t matter too much what they read, as long as they were enjoying it. Just getting them to realise that it is enjoyable, and not a tedious chore, can be a major hurdle.
