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

Example Input: Beware of the size of this book!If you are expecting to receive a regular size art book, you will be extremely disappointed. The book measures 7.5 x 9 inch and is thinner than my pinky finger.However, if you are just interested in the content, there is a lot to look at and to read.
Example Output: Negative

Example Input: I've bought this book, underlined every hint of symbolism, found all evidence of romanticism, followed every quote involving thematic oppositions, and noted every example of Pearl's rebellious nature and social alienation, but I cannot find one positive aspect of this novel that makes any of my hard work feel rewarding. The only way this novel could give me a warm feeling is if I place it in a furnace.
Example Output: Negative

Example Input: My wife was skeptical about purchasing a new toy. Until now, she had not cared for any toy we have used. We ended up buying the Jack Rabbit because so many of our friends recommended it. We chose to try it first in the jacuzzi...it only took about 90 seconds. The next morning, we tried it in bed with the same results. My wife is now a huge fan of the bunny ears! I highly recommend this item. But it now!!!
Example Output:
Positive
