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

Now, solve this: Man, hardly have I watched a movie this long (one hour and 53 minutes) that portrays the leading character in every (I mean, every!!) single scene, every single second of the whole movie!This is a bonus if you are a Diane Lane fan (and who is not? The woman is simply gorgeous, besides being a very good actress!), but otherwise youl will be imersed in a chick flick all along, and a bad one by the way, one that will lead you absolutely nowhere.
Solution:
Negative
