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

Example Input: Ugh! What a steaming pile of predictability this movie was. At least I didn't pay to see it and was able to read a software tech manual while "watching" this. The plot is thinner than the paper it was written on and the acting, well its typical Michael Bay which means you can see more believable productions at you local high school. It was easily an hour too long and the special effect have been used hundreds before. I think the saddest part was hearing Lenard Nimoy as Optimus Sentimental, I mean Sentinel. Gratuitous sci-fi pandering at it's lowest.
Example Output: Negative

Example Input: You aren't saving any being this adapter. I purchased this for a 12" G4 Powerbook. The power it supplies goes on and off constantly. This can't be good for the computer. It certainly doesn't charge it. Don't waste your money on this Macally adapter. Try to find an original Apple adapter if you can.
Example Output: Negative

Example Input: The cushions fell apart- split in half and does not stay on your feet. Do not buy- very poor product.
