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: Do not buy this toy. If you are given this toy as a gift, return it for store credit. This is a flimsly and poorly designed stack of platic and paper. The secret door doesn't work, the elevator doesn't slide and toys get stuck in there. The suggested 10" batman doesn't work with the zip line, bungee or even the elevator. The add says "Using new adhesive technology, you can set up the Batcave on just about any wall" so they want us to glue this thing on to a wall.Please don't buy this toy.
Example Output: Negative

Example Input: I too have the same problem most recent reviewers have had: when I plug the charger in, it cycles between charging and not charging every two seconds. The computer doesn't end up charging.In addition, the version I have doesn't look like the picture on the Amazon web site, and doesn't have the power LED.Clearly there is an epidemic of defective chargers. And we, the customer, have to go to the hassle of obtaining a return authorization and sending it back.I notified the seller. I am also going to notify Amazon to research this topic, and take the product off the site until they can resolve the issue. Other than this charger, my experience with Amazon has been exemplary.I strongly suggest that if you too have bought one of these chargers and have had trouble with it, please post here.
Example Output:
Negative
