Bit harsh to refuse plaudits to Dickens and Shakespeare because children don't like them. As MMario says WS wrote for the populist market of his day. Dickens novels were frequently written in episodic form for popular magazines of the day. He made a fortune travelling the world reading his work in public. The criticism should lie with educational systems that force feed children unsuitable literature. Pratchett is stuffed full of literary and classical allusions. Why don't we see his works on school curriculums? Might make some of the kids want to explore his source material.
