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

Example Input: Hawthornes The Scarlet letter is an okay book. It has an okay plot and okay characters, but the book is not one for teens of the 90's. I had to read this book for my English teacher and to tell the truth if it were not graded I would not have read it. The teens of today do not want to read about the ancient customs of puritan society. If it had been about the scandalous affairs of Hester and Rev. Dimmsdale it would still be a best seller. I think this book should be only read voluntarily. If you are thinking of reading it you may need to reconsider.
Example Output: Negative

Example Input: There is no plot. What in the world did I just watch? Nothing made sense, from beginning to end. I've lost my faith in humanity after watching this...
Example Output: Negative

Example Input: Any problem listed in previous reviews, I encountered with mine. At which point I discovered one more weakness of this mp3 player.It does not fare well against a hammer.
Example Output:
Negative
