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

Example Input: This book was brand new when I received it. However, it did not arrive for 20 days after I ordered it.
Example Output: Negative

Example Input: The book covers several generations, so with each generation you have to re-learn all the characters. It is difficult to keep track of who's who when every time you get to know the cast, 200 years suddenly pass and we're in the middle of a new crisis. I didn't read the whole series because of this -- it was obnoxious.
Example Output: Negative

Example Input: I purchased three of these and within 1-2 months, ALL three of them "broke". The seams on two of the beds broke, leaving a huge bulge in the middle of the bed and the seams of the third bed kept coming apart..Im not sure how many holes I had to cover but way more than their repair kit allowed for. After contacting the company and starting the refund process, I was told that since they were bought through Amazon I wouldn't be able to receive a refund. TERRIBLE CUSTOMER SERVICE! Yes, the beds are $35.00 so I definitely got what I paid for but can't believe how cheaply they are made. DO NOT BUY THESE PRODUCTS!!!! Spend more to get more bang for your buck!
Example Output:
Negative
