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: Yes, all the reviews are correct: This is an excellent writer detailing some of the most gruesome killings of all time. It is the fastest 650 pages you will ever read, I gaurantee it.One note: This book might also be called "Vincent Bugliosi: The Man Who Brought Down Charles Manson And Lived to Tell About It." That is to say, Bugliosi is evidently proud (rightfully so) of his accomplishment as the lead prosecutor on the case. And he pretty much makes mincemeat out the intellect of the LAPD and the defense attorneys involved. But like any good prosecutor (and Bugliosi is most certainly that) he has quite a bit of evidence to back his charges of ineptitude. If I were Kanarek, or a Tate detective, I'd be pretty embarrassed knowing this book is an all-time bestseller.But who are we kidding, this is the definitive book on Tate-Labianca. A truly fantastic read.
Example Output: Positive

Example Input: this is the worst comedy evericould tell this was an adam sandler movie right from the startit its a compilation of all the weak jokes from his past movies and albums, actors and songs put together to make a very dissapointing comedy. Had i known this movie was so bad, i hoped someone would have brought it TO MY ATTENTION YESTERDAY!!!!
