Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: Wonderful book that I discovered in junior high. Several years later I bought a copy and this novel has become one of a treasured few I read again every year. The central character (indeed, practically the only character for most of the book) grows so much during her experience that you remember her life changes long after you put down the book. As always, great fast-moving, realistic storytelling from Harry Mazer.
Solution:
Positive
