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

Example Input: Unfortunately, there is a major problem with the sound on this album and it's so bad that it makes this album unacceptable and a waste of your money. What a shame! Although I can clearly tell there was nothing wrong with Eddie Fisher's performance of this set of songs; the sound quality (and probably the mastering) of these tracks is every bit as poor as the other reviewer states that it is.Therefore, I would recommend one of two alternatives. Diehard Eddie Fisher fans will probably want both! First, there is the very good (even though it's currently out of print) CD entitled "Songs for Christmas" by Eddie Fisher which has two bonus tracks by Frankie Laine. Second, there is the CD that contains the music from three of Eddie's record albums entitled "Eddie Fisher Sings;" "I'm in the Mood for Love" and "Christmas with Eddie Fisher." In short, you'll be much better off with one or even both of these two other albums.
Example Output: Negative

Example Input: This book, published in 1996 and half of which is a directory of shops, was bound to be outdated months after publication much less ten years after, as it is now. Hence the four stars instead of five.Given that, the first part of the book is crammed with a precis or summary of Flusser's recommendations that he has used several hundred pages to expound in his other books ('Clothes And The Man', 'Dressing The Man') and makes the book worth the (used) book price.I do not understand others who warn against this book because they think it is not objective enough! This is a book written by Flusser so of course you will get his subjective view. Had it been written by a committee of tailors, well then, I would expect a more balanced view, but it is not. It is up to the intelligent reader to understand they are getting a product of one man's opinion and then proceed accordingly.
Example Output: Positive

Example Input: Not only am I a fan of Dolly Parton, but a huge fan of bluegrass. Dolly has once again shown her versatility in delivering the essence of bluegrass, and adding so much more with her unique voice and harmonic orchestrations. This album is a buy whether you are a Bluegrass, Dolly Parton, or Folk listener.p.s. I'm still only halfway through my first listening of the album as I'm writing this!
