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

Example Input: I've read several other Deborah Smith books. In my opinion Blue Willow was the best. Sweet Hush was by far the corniest book, I've read in a long time. The phrase "Sweet Hush" must have been at used at least 100 times in the book. The main character "Hush" was predictable and one dimentional. If you enjoy Deborah Smith books, I would skip this one.
Example Output: Negative

Example Input: I'm no great fan of bluegrass or country, but this release intrigued me because - like many people, I suspect - I have a soft spot for Dolly. "The Grass is Blue", though, really is as good as the other reviewers have said.
Example Output: Positive

Example Input: I wouldn't have purchased this movie if I didn't like it, so obviously its a great movie. Hardly even miss Megan Fox. Great special effects, great action, funny.
Example Output:
Positive
