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

Example Input: I think a couple of people are missing the point... The reason this is out is (I heard) they didn't have the cash to finish AV Vol 2, so this would generate some cash AND be of interest to their core fans. Plus, the demos ~are~ a good insight to their creative process.... I ~love~ to see the rough drafts... If you're just waiting for Vol 2, why did you buy this in the first place?
Example Output: Positive

Example Input: I received the product in a timely manner. It was as advertised. I have used it a number of times and it works well although I haven't gotten the results from it I had hoped for. No fault of the seller or the product though.
Example Output: Positive

Example Input: Unfortunately, I did not like this book. I found it difficult to read and boring, even though it was recommended by a friend..
Example Output:
Negative
