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: Firstly, it is incredibly important that you DO NOT use the bundled software for this scanner. The program is confusing and terribly disorganized. I have had several issues with using OmniPage, Readris, and Microsoft Scanning software bundled with Windows. While image quality is good, especially considering the speed of the ADF, the ADF gets jammed during almost every scan with these programs.I strongly recommend that if you have purchased this scanner, use Adobe Acrobat 6 or later. I am using 6.0 Professional and it works like a charm. The file size is extremely manageable (300K for 15 pages) and is quite readable.If you have not purchased this scanner, DON'T. While I don't have any recommendations for other models or brands, I will suggest strongly that you avoid this one. It has been quite an experience, causing me to use Kinko's and similar because I couldn't get this scanner to work. Since using Acrobat, most issues have been mitigated to a tolerable level.
Example Output: Negative
