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: I own the boxset of Nirvana and its good. It took awhile to come out, but it was worth it. Now this? A cd that takes the best moments from the box and adds three new tracks? How much more will fans have to suffer? Whats next for fans? Kurt's legacy is like 2Pac and being crapped on but his greedy friends and family. I cant wait for Scott Stapp to produce the next Nirvana "lost cd"!
Solution:
Negative
