I decided to read this after hearing of the author's death and seeing this book's popularity. Unfortunately, I didn't enjoy it. The story seemed pretty pointless to me. There's no moral and the boy learns nothing. It's a snapshot of a boy's imagination. However, I did enjoy the illustrations of the monsters. Having been published in 1963 perhaps this book is a product of its time, lovingly remembered by those who were read this as children and who wish to pass it on to their own offspring. Or maybe it just wasn't for me.
