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

Example Input: This is written by a 43 year old male who is a true film fanatic. I love all the great directors- Spielberg, Hitchcock, Wilder, Kubrick, Landis, Scorsese, etc. etc."The Unbearable Lightness of Being" was one, if not the most tedious films, I have ever had to endure. Why is it so talked about is beyond me unless, there is nothing definable to discuss. The scenery was bland, dialogue uninteresting and unengaging, even the shots were dull.It's the first film I ever returned to Amazon...ever.When I took Cinema History in College, the Professors I had kept talking about this film as a "must see/ will change your life" sort of thing. Curious, as we never saw it in class (must have been the explicit erotic nature it has at times). Now I think they wanted the girls in the class to see it on their own, because they may have wanted to discuss it with them personally after the class was dismissed, if you catch my drift.I would pass on this one-big time.
Example Output: Negative

Example Input: I've heard it said that this is Kerouac's greatest novel. I still say that honor is held by On the Road, but this book is just as good. And it is his most spiritual novel. Kerouac combines his talent at writing with his philosophy of life and what you have is a powerful tool to enlightenment. This book should be read on at least two levels, as a work of great literature and as a theological tool. I can't recommend it enough.
Example Output: Positive

Example Input: I was very disappointed in this book. I have found shop set up for effecient layout and dust collection to be the most important aspects of my woodworking. I am always looking for new and innovative ways to be as effecient and effective in these areas. I could find no difference in this book and the earlier version it replaces. Even the photos are same outdated photos that appear to be taken in the late 70's used in the 2001 release. Please, Taunton, don't insult your readers by continuing to regurgitate the same information with a shiny new label in an attempt to sell more books. Please strive to produce new and relevant photos and information. Your books and magazines are already some of the most expensive, it would be nice if the quality matched.
