Instruct: Classify Amazon reviews into positive or negative sentiment
Query: A huge waste of time!

Very, very disappointing. This will teach me never to listen to reviews....An epic piece of ...., incredibly and unnecessarily long, very predictable, characters are too stereotypic. A trashy novel set in the middle ages....really, why? Pornographic descriptions of sex which I really did not enjoy reading, and the detailed discourses on cathedral engineering didn't get me, either. I should have borrowed the book at the library and not paid for it to have it on my kindle...
