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

Example Input: What a junk. Every time NOMAD thinks the file is corrupt the OS freezes. The only way to recover is to plug the power cord and go into recovery mode. So if you happen to be out of the house and you have a frozen OS you can't use NOMAD until you get home. After OS froze twice on me in the subway I returned the jukebox.
Example Output: Negative

Example Input: This book was interesting with great promise. The premise was fascinating but the writer fought with herself throughout. She spent a great deal of time on the flora and the fauna. There was always a paragraph on a bush when a sentence would do, a sentence on a tree when a word would suffice. The characters were well developed. Over all it was a good read.
Example Output: Negative
