Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: Mercedes Lackey contributed to a series I'll refer to as the Merovingian Nights Series, set in a universe invented by C.J. Cherryh. Mercedes's ORIGINAL contribution to the Merovingian Nights series is a far better read. The Shadow of the Lion was a major disappointment to me, not to mention I could have spent my money more wisely on another book. There should have been a warning posted on the cover or flap that if the reader has read the Merovingian Nights series, this book will offer very few surprises. Shame on you Ms. Lackey!
Solution:
Negative
