In this opinion piece by renowned late literary critic Harold Bloom, we see him levy the following charge against Harry Potter and the Sorcerer's Stone:
I went to the Yale bookstore and bought and read a copy of “Harry Potter and the Sorcerer’s Stone.” I suffered a great deal in the process. The writing was dreadful; the book was terrible. As I read, I noticed that every time a character went for a walk, the author wrote instead that the character “stretched his legs.” I began marking on the back of an envelope every time that phrase was repeated. I stopped only after I had marked the envelope several dozen times. I was incredulous. Rowling’s mind is so governed by cliches and dead metaphors that she has no other style of writing.
"Several dozen times" means "at least 36 (=3*12)" times, because "several" while a vague quantity word, always means at least three. However, if you actually download the ebook version of Harry Potter and the Sorcerer's Stone, you can count the number of times the word "stretched" occurs throughout the book, and it's seven. And none of them take "his legs" as a direct object.
What was he thinking when he thought of levying a false charge against J. K. Rowling? IANAL, but if I were in her shoes, I would have filed a civil suit for B.S.ing all over my work.
