My kids loved Roald Dahl books I think they pretty much read all of them. When they were very young I read the Minpins as a bedtime story, my older one was completely captivated by The Witches and it was always one of his go to books to read again and we all loved his Revolting Rhymes, just so funny. I found his material far superior to David Walliams books which my granddaughter seemed to like at one time. I know Roald Dahl has had certain accusations levied at him, I'm scratching my head trying to think of what would need to be censored in his books though, like the Potter books they captured the imagination of many a child and children need that if they are to become lifetime readers and not be turned off at the first hurdle by books that they find dull and don't fire up their imagination. Some of the suggested reads, not all, they brought home from school did just that, turned them off.
My childhood beloved books, The Blytons suffered from the same fate and whilst I think it was absolutely justifiable to take the N word out of the title of one of the Christie books, I think it should be remembered the most writers were of their time and often their class and that is reflected in their writing.
