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

Example Input: If you paid for this product, you overpaid. Granted, the original, out-of-print dvd of The Bikini Carwash Company sells for exorbitant prices, so my suggestion is to just download it for free through torrents and cut the video pirates and video scalpers down to size. If anything, buy the European PAL version, which is also uncut and uncensored, and available on the North American Amazon as well.
Example Output: Negative

Example Input: As well as a trilogy that is as far-reaching as it is set in a far-distant time with characters and galactic backdrop unrivaled by any other book. Definitely one of the great science-fiction classics just like "Stranger in a Strange Land", "Childhood's End", along with modern-day cyberpunk like "Neuromancer", "Count Zero", "Prey", "Cryptonomicon", "Snow Crash", "Darkeye: Cyber-Hunter", etc.
Example Output: Positive

Example Input: My step-daughter got a set of glasses, and 3 family members cut themselves because they broke as they were washing them. I thought I'd replace her [poorly made] and dangerous ones with these, due to what I thought of as the quality name brand Anchor Hocking. She already got a different set of glasses, so I kept them for myself. One was broken in the box when I opened them up. I thought no big deal. I started using them, and within a month, of the 16 total, I am down to only one large one and four small ones. I also have 2 less butterfly stitches and 6 less bandaids in my cabinet. My daughter informed me that these were the EXACT glasses she experienced the same problems with. I am sorry to discover that Anchor Hocking is no longer going to be associated with quality, as it used to be in the past.
Example Output:
Negative
