Quite simply Jonathan Jones has arrogantly snubbed an author who is popular the world over, shortly after his death and in the same week his last novel has been released. 

In the article Mr Jones states that he has never read Terry's work but seems to have a negative opinion on it. This is populist click bait journalism at its very worst and Terry Pratchett deserves more respect than this kind of low brow feeble journalsm.
