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

Example Input: The book was boring and to far fetched to be entertaining. The characters were not believable and left me with wanting to many unanswered questions. The author took to many liberties with facts. All in all, I just didn't care for the book, skipped thru pages to end it so I could go on to more enjoyable reading. Amazon offers so many options and choices that I'm bound to pick a lemon once in awhile. I always read the brief description of the book before I buy but in this book that wasn't enough.
Example Output: Negative

Example Input: Very intuitive in explaining the basic concepts and the fundamental and widely used methods in continuous-time finance. No deep background in math is required to have a good grasp of this book. I believe it is intuition rather than fancy skills that is important to build up interest and passion for studying a hard topic such as continuous-time finance.
Example Output: Positive

Example Input: I will never understand how "Classics" become Classics. So far for school i Have had to read far to many Classics. Dickens should be glad he is dead and does not have to read his books because they would probably kill him out of sheer boredom...Hawthorne creates an ok tale, but really? It gets dragged out and is suppose to be realistic. Then he throws Pearl in there, she is like some super-human and belongs in fantasy. I never really did believe in the whole 'they completely ostracized her but let her stitch everything.' That is just a bit hypocritical, either she was excepted as prat of the society *which she was not) or she wasn't (which she almost was. See that just doesn't make any sense. The story is suppose to show how unforgiving the society was, but it doesn't. It is better than Dickens, but then again everything is.
Example Output:
Negative
