Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: This album is worth the wait. Great vocals accompanied by rocking fuzzed out riffs. Sounds like the perfect cross between Unida and Kyuss. The cd hasn't left my player yet. The only problem I have (which means 4 stars instead of 5) is that its fairly short. It really only has 7 tracks that total under 30 minutes. That aside, any fan of this genre of music will love it. The cd flat out rocks all the way through.
Solution:
Positive
