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

I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: Despite the many reviews from folks who had to return one or more Sansa Views before getting a functional one, I figured the manufacturer must have cleared up their quality problems to stay in the market. Wrong!!!!My brand new Sansa View 8 totally stopped functioning about 20 minutes into its first use. I'm very disappointed to have waited for my order to be filled and now must wait again for a replacement. I'm more than a month into my purchase and I have nothing to show for it but a paid bill.Amazon has not stepped up at all, either. The order was filled by a vendor whom I've never heard of before. Amazon refers buyers to that vendor's customer service and takes no part in satisfying the purchaser.Lots of room for improvement on the part of all three providers.
Solution:
Negative
