Out of all the characters or books you have created, what is the most outrageous or hilarious criticism you’ve received about each book or main character?

Since my fiftieth-first book is about to be published I don’t have time or space to research and/or document all the criticisms, but overall the most striking and amusing criticism I receive isn’t so much a single criticism as the fact that for almost every book I’ve written someone somewhere has claimed that it’s fluff or simple and someone else has found that same book deep and/or thought-provoking. By the same token my style has been described as both simplistic and complex and at times poetic, even for the same book at times.
