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

Example Input: It's pretty nice and comes with a little book with interesting proverbs too. I'm not sure if it really helps to relieve stress but it's makes a fun distraction once in a while. The only complaint is when other people play around with it, they always spill sand out the box..
Example Output: Positive

Example Input: The movies get to me the same day they hit the stores and I dont have to drive to get them.
Example Output: Positive

Example Input: I got this player for Christmas and it immediately had bad screen problems, the LCD screen would freeze or make thick dark lines. The rewind bar doesn't work either! you can rewind it and the seek bar will show it rewinding, but it'll resume right where it left off! I only give this player 2stars just because it's ease.
Example Output:
Negative
