Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Gee! What does it mean?

All of the reviews are either extremely negative, or extremely positive. Seems like the system really does work, if you care to have a good look and read through. The title of this "book" should be "Buy This Book & Make ME a Millionaire". Like a famous coach once said, "Success without character is like a meal without seasonings. It will satisfy your hunger, but it won't taste good."
