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: Like the ones before, this book is a solid forensic and police procedural. A death row inmate is executed and his fingerprint later shows up in a current crime scene. How could that have happened? I particularly enjoyed seeing Kay's niece, Lucy, again, as she is 17 now and her own person, no longer a child. Lucy's computer skills continue to amaze. I look forward to reading the next in the series!(Note: There is a continuing bad guy introduced in this book who appears in the next two installments as well. I'd recommend reading this book before The Body Farm and From Potter's Field)
Solution:
Positive
