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

Example Input: All the elements of a great movie. What can I say, I love to study the elements of war, and I enjoy a good love story along the way. This movie was a great introduction to the role airplanes had in the first World War. Featuring the story of the Lafayette Escadrille, and the role Americans had in the early aerial engagements. The story also allows those who have little knowledge about early technology to understand that it was very rudimentary. (Using hammers to clear your machine gun comes to mind.) The soundtrack was very well done, and the needed animation(?) was excellent as well. I highly recommend this movie.
Example Output: Positive

Example Input: As most people readers know, Jack Higgins has written many fine action-packed books. However, this book reads like a twelve-year-old wrote it. The characters are so transparent they could be ghosts.The author and his publishing house must really need the money to rip of the public in this manner. This is the last book I read by this author. One can only rest on his laurels for so long. I'm glad this book was handed down to me or I would have written a really nasty review.
Example Output: Negative

Example Input: My 5 year old son received this as a birthday present, and it is headed right back to the store. The legs do not stay on, it falls over when touched, with or without the legs, there is a missing door, the elevator gets repeatedly stuck. As much as my son loves the idea of this toy, he has given up and resigned to playing with his other toys because this one is garbage, and a pure waste of money.
Example Output:
