Anyone who thinks that EB writes repetitively and badly should read the Barney Story, The Rub-a-Dub Mystery.
Barney (for those who don't know) lived with his circus Mum. She ran away from his dad because she assumed he wouldn't want her, being a nice middle-class chap and her a circus girl.
When the series begins Barney's Mum has died, and he's always hopeful that he'll find his dad but he has almost no information about him, except I think he was also called Barney, if I remember rightly.
In The Rub-a-Dub Mystery, Barney is taken under the wing of a chap who says he might have an idea about his Dad. Of course he's thrilled and he's willing to go along with almost anything to help. So when he's told that his Dad is coming, and wants to meet him, he willingly takes the package to give him and goes to meet him.
But when he hands over the package, and tries to speak to the man who he believes is his Dad, the chap knows nothing about it, and he's brushed off, devastated and left.
Being Enid Blyton, naturally he does manage to meet his Dad, who is delighted to find him, but that's (almost literally) another story.
The writing is a little old-fashioned, as you'd expect for a book written in early 1950s, but it is very well written.
When people accuse her of racism/sexism etc look at the era in which it was written. What she was writing is no different from many other authors at the same time who haven't had those accusations and attempts, often badly to "update" the stories. Arthur Ransome, for example, the girls always do the cooking, and John tends to do the majority of the sailing for the Swallow.
One of the heroines in The Chalet School uses the term "working like a XXXX". I've never heard either of them being accused of being sexist/racist.
Jaqueline Wilson wrote a book about a girl being groomed by her teacher, as though it's a love story - there's no condemnation of the teacher. She wrote that in 2006 and it's still in print with no alterations.
So why does Enid Blyton get so much of the criticism when there are others that are similar?
I suspect one of the issues is that children reading them feel that it's today, about them and their friends - so they forget that they're written in history and judge them against today's standards.
And by today's standards, yes we do disagree with some of the standards they had 75 years ago. Just as in 75 years time our great-grandchildren will be recoiling in horror about what we think is very progressive currently, thinking that because their standards will have evolved too.
I'm sure they will judge us, just as our generation has judged history.
