Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Complete WASTE!

I think the guys who sell the book must be writing all the good reviews for it. This book is horrible. It is a small photocopied pamphlet, not even worth the .10 they probably paid to print it. There are so many other better books out there, in fact you can't even call this a book. I cannot imagine that anyone who purchased it would have a single good thing to say about it. I also think it is funny that all the reviews are either one star or five. Clearly a dishonest bunch of guys working to make money. DO NOT BUY THIS BOOK! Burn your cash instead if you must.
