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 Input: Works fine on the PowerBook G4. Doesn't have an LED to tell you it's on and, of course, doesn't have a smart plug to show charging status.
Example Output: Positive

Example Input: Every reader of the Frozen Republic will find something to disagree with, but if you have an open mind, you will find that Lazare has many good points about America's government not being the be-all, end-all of democracy.The Frozen Republic is a history of Constitutional (and para Constitutional) problems that America has faced and a description of Constitution worship as America's religion. There is very little on comparative government or a blueprint for change. Lazare appears to favor a parliamentary system, but he does not spell this out in any detail, or say very much about voting reform.
Example Output:
Positive
