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

Example Input: This movie is just plain sad. In addition to mediocre acting, the special effects were just as bad. In one scene you could plainly see the safety wire connected to the motorcycle. Bad diologue and senseless nudity made the film even worse. The plot drug and the resolution could have been solved a little sooner than it did. They came up with a lame chase scene with an airplane cruising on the ground after a motorcycle. Maybe that was a last ditch effort to make the movie a little bit more exciting. The only slightly interesting character was played by LL Cool J. His on camera presence is always rather captivating to me. It also carried him through a poorly written character. Since most of the movie took place on the track, there was more of the game than I could really put up with. Avoid it.
Example Output: Negative

Example Output: Positive

Example Input: This was one of my favorite books assigned in school this year. I like the exciting adventures of this cannon trek from Fort Ticonderoga to Cambridge, MA. I liked how they crossed the ice with all of those big guns. When the last gun crossed, the ice cracked, but they were able to get the big gun out.
Example Output:
Positive
