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: This is a good movie. It had the misfortune of coming out around the same time as Julia Robert's feminist 'Mona Lisa Smile' and being sometimes confused with that film by critics. This is not a feminist, male-bashing movie. And it isn't entirely a 'chic flick' either. Diane Lane is apparently very picky about the roles she plays and the films she appears in. This is another good choice for her.There are plenty of reviews here telling what this film is about. I'll simply tell you that I bought the DVD for my wife, but I usually watch it with her. It is a good movie.
Solution:
Positive
