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: Tess of the D'Urbervilles is one of the worst books I have ever read. I read this book in high school, though I am now in college, but don't discount this review because of that. Tess has absolutely no backbone. She pines away for stupid Angel who is more cruel to her than the guy who raped her in many ways. I know women weren't as strong at that time but even so, she is still pathetic. When she tells Angel that she would jump in the river and kill herself for him, I laughed out loud! Tess is a spineless, pathetic excuse for a human being. She needs to take some lessons from Jane Eyre, a hundred times better heroine. Also, Hardy describes the same stupid valley so many times that the book drags on forever and seems like it is never going to end. I disliked all of the characters so much, that it made the book have not one redeeming quality to it. If you want to read a Hardy book, read Mayor of Casterbridge--it is much better!
Solution:
Negative
