Query: Pretty Worthless

Griswold's treatment of the books is disappointingly shallow. He makes a number of undeniably true observations about what children like, how they behave, what they seek out, etc - and then notes that various well-known books satisfy those desires. E.g., children like to feel snug, like to enclose themselves in small spaces - and guess what? that's exactly what you find in various children's books. Griswold doesn't devote much time to asking "why?" or to explaining the significance of any of these desires. The book is enjoyable but by the time you're done reading the author's very superficial discussion, your reaction is, "well, I could have told you all that off the top of my head."
