The American Library Association just released their list of the Top 10 Most Challenged Books for 2013 (http://www.ala.org/bbooks/frequentlychallengedbooks/top10#2013) and, once again, the Captain Underpants series topped the list. So, between that ranking and the fact that our son loves them, I had to read one.
Aside from the grouchy old me wanting Pilkey to spell things right, I thought the book was fine. I laughed out loud once and grinned a few times. The illustrations are great, and I like the idea of an Invention Convention.
Most importantly, children read them. And re-read them.
