Query: Childish

I want to write something constructive to explain why this book was such a waste of money and time, but find myself sitting dumbfounded that I listened to someone who told me it was good. Watch a cartoon if you want characterizations and plot befitting a 10-year-old--it's shorter and cheaper. Factual errors are the least of many troubles. It distresses me that people are taking this as a well researched book.
