'The Witches' (1990)
In reference to "The Witches," one reader said: "I love most of Roald Dahl's children's books, but I can't stand 'The Witches.' They are portrayed as child-hating monsters with bizarre, grotesque features such as no hair, claw-like nails, etc. Their young victims meet with such unpleasant fates as transformation into stone or animals or being trapped inside a painting. The main character discovers the witches when they have a convention under the guise of the Society for Prevention of Cruelty to Children. (Let's introduce children to the idea of a sinister conspiracy theory at an early age!) The story ends with a plan to use the witches' own mouse-transformation potion against them--so that they will be trampled and killed by other people!"
