I won't stand for Pilkey slander. I have worked in education. His books are certainly silly, but they are indeed a very functional gateway to get kids to enjoy reading on their own. Yes, they are immature, they are for kids. No, they won't make your kids into delinquents, especially not if they get your kids to read a lot more than they would have. I think it's important to show kids that reading doesn't have to be all textbooks and dry academics, it can be fun and enjoyable, because why would they ever read of their own volition if by their perception it isn't fun at all?
