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

Example Input: All the other bad reviews are good enough for me. I'm just adding my vote on this one as a one star. I can't fathom how the ones who ranked it as 5 stars saw the same movie as I did. The best thing about this movie was returning it to the Red Box I rented it from.
Example Output: Negative

Example Input: The adapter worked fine for my power book g4 for a few months and then it broke. Nothing physically happened to the adapter for it to break, but suddenly it just wouldn't charge any more. What's interesting is that the blue light on the brick goes on when plugged in to a power source, but if I plug the cable that attaches the computer to the brick in, the light goes out and it doesn't charge.
Example Output: Negative

Example Input: I inflated this air bed for a guest who reported how comfortable it was. The twin fitted sheet worked great and didn't slip around with the flannel surface. The installed inflation/deflation pump also worked great and was fast. My guest used the air bed for an entire week, and it never lost air or got soft. My only criticism is that the static on the rubber underside did pick up some loose dirt and dog hair that was on the hardwood floor where I placed the bed.
Example Output:
Positive
