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

Let me give you an example: I've read this book with much expectation, it was very boring all through out the book
The answer to this example can be: Negative
Here is why: Review writer does not like the book because it was boring, therefore it is a negative review.

OK. solve this:
This compilation contains some of the best jazz guitar ever in songs like Scotland I, the Jam with Albert and Yin. Unfortunately it also digs up silly tripe like Eyes of Love, Planet End, Adam Smasher and Rene's Theme. The shorter compilation, the Essential Larry Coryell is less expensive, more consistent and manifestly superior to this double CD.
Answer:
Negative
