What happened?

I have been reading Captain Underpants for seven years, from the age of six. I own every book until the tenth one. The deaths of Crackers and Sulu shocked me and I swore that I would never buy another Pilkey book. Then I thought ‘maybe the eleventh one is going to be better.’ So I got it from the library.

This book is not like the first nine, filled with fun childish humor. It is written for a much older audience and is not funny anymore.

Violince is inferred as ‘too shocking and disturbing. It will give you nightmares for weeks.’ Hello, Mr. Pilkey. The whole point of your series is that it is a farce on the violent superhero genre.

Later in the book, there is a scene where all of George and Harold’s teachers take their clothes off and start sliding on the floor, finally resulting int he pantsing of a police officer and them going to jail. Mr. Krupp, the alter ego of Captain Underpants, goes to an insane asylum. That is not right. Mr. Krupp is a terrible person, but it still shouldn’t be that way.

Near the end, George and Harold are talking about the breeding of a boinic hamster and a pterodactyl. There are some infrences to dirty innuendos, another first.

Congratulations, Mr. Pilkey. In the course of two books, you have turned my favorite series, a whimsical comedy, into a violent and inappropriate abomination to the name. You have lost a faithful reader. After this, I will never check out any of your books from the library, buy them, or recommend them to a friend. You were the best at writing for younger audiences of ages 8 through 11. Writing for children aged 12 and 13 doesn’t work.
