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

Example Input: This book, published in 1996 and half of which is a directory of shops, was bound to be outdated months after publication much less ten years after, as it is now.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: Product reviews are very subjective. Based on the reviews of this boot I hoped for a great boot at a fair price. Instead I found the boot to be subpar in terms of comfort. They shoes were stiff and far too 'roomy'. My feet where floating inside them. I returned them immediately. I've had far more comfortable boots right out of the box.
Example Output: Negative

Example Input: This product looked fun but in reality was very uncomfortable and it vibes only at the middle! It's also very large (long) and didn't fit very well! Anyway, in summary, a neat idea, but not a staple or even fun for a one time use!
Example Output:
Negative
