That's a...really weird condemnation. I certainly haven't read all of them, but every Newbery Medal nominee I have read has been excellent.
If I wasn't already reading Tom Clancy and Robert Ludlum and Tolkien by that point, that kind of horseshit might have turned me off reading altogether at around 11-12.
