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

Example Input: A really fun book, well worth your time if you like Pratchett. None of our old pals [Rincewind, Gaspode, Vimes, Susan] put in an appearence [other than the guy WHO TALKS LIKE THIS and an old monk with a broom, and they but briefly], but it does add some info to the overall Discworld mythology, and provides some laughs as well.
Example Output: Positive

Example Input: As most people readers know, Jack Higgins has written many fine action-packed books. However, this book reads like a twelve-year-old wrote it. The characters are so transparent they could be ghosts.The author and his publishing house must really need the money to rip of the public in this manner. This is the last book I read by this author. One can only rest on his laurels for so long. I'm glad this book was handed down to me or I would have written a really nasty review.
Example Output: Negative

Example Input: I first found this book when i was little--and yeah, then it scared me more. I found it recently in barns and nobles, and wanted to buy it to re read it. Big mistake.This book is more hysterical than scary to me. I didn't even feel a little scared. Big disappointment for me. my advice? read it when you are younger, it might acutally be scary then.
Example Output:
Negative
