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

Example Input: I think AFX's take on "Run the Place Red" is incredibly fun -- it makes me want to jump and shimmy each time I hear it. Now, I'm not a huge fan of ragga, but ragga-jungle-drill 'n' bass? I think it's a genius combination, one that only the demented mind of Mr. James could discover. You can barely understand the vocals beneath the percussion -- they're more flavor than anything else. As for the two noise tracks, they're rather interesting the first time around (not to mention intense on the squeals), but I don't think they stand up to repeated listens. Mostly because I don't want to go deaf.
Example Output: Positive

Example Input: not nearly as good as her usual work if your hoping to hear her forget it it is a pale comparison with authors who don't have her style
Example Output: Negative

Example Input: Cities of the Red Night is William Burrough's magnum opus, the most sublime manefestation of his genius. From the opening chapter titles and hallucinatory invocation to the exquisitely fashioned closing dream sequence, each word bears the stamp of the studiously enigmatic visionary stylist. This novel impressed itself to the point that I met one of the characters in a dream, a truly disorienting experience. Sure, it's disjointed. Innoculation to the parasitic authority of the word virus, to see and feel in another medium, whaddaya think the poor guy's tryna say here, anyways?
Example Output:
Positive
