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

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 didn't much care for "On The Road" after the first 50 pages or so and i'd pretty much thought that this great "Beat Writer" was nothing but hype, but after reading "The Dharma Bums" I now believe Kerouac is one of the greatest writers of modern times. READ THIS BOOK!!!!
Example Output: Positive

Example Input: I used these once then used a Kleenex to wipe one lens that was a little smudged. I have microscopic vision and I noticed it was scratched AFTER I used the Kleenex, so to be sure, I used it again and sure enough, it scratched the lens some more. I compared the 2 lenses and the other lens looked pristine, whereas the one I used the kleenex on was scratched all over! Very low quality lenses! Unusable after one use!
Example Output:
Negative
