Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Example: I've read this book with much expectation, it was very boring all through out the book
Example solution: Negative
Example explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: I really enjoyed this new author! The hero and heroine seemed pretty evenly matched when it came to wits, and the sex was hot! Add in their jobs, a strange case with a dog, and medical mishaps, and I thought it was a funny riot! I was glad there was a HEA!
Solution: Positive
