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

Problem: This book is an excellent choice if you want three things: a great heroine (in the form of Ayla), an epic adventure (this is the beginning of a long series), and lots of fascinating insight into the ways of prehistoric man and the Neanderthals. I had never read a book based in prehistory and I was pleasantly surprised. The author's careful description of the tribe's skills held my attention, and I truly enjoyed watching the human girl, Ayla, become a woman among a Neanderthal tribe. I recommend this to high school students and older.
Solution:
Positive
