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

Example Input: Paxton Quigley's book is a compliation of parts of other books on firearms self protection. It's a bit overdone, and probably would scare the average woman thinking about protecting herself. Women seem to have special problems protecting themselves. They usually do not want to hurt anyone, and they will do all most anything for a baby or a family member before they will do anything to protect themselves. However, women that are able to continue to practice with a hand gun, usually become quite proficent. They know that they don't know, and they listen to instructions. Most men think they know it all already.
Example Output: Negative

Example Input: We got our PowerBook in July of 2003 and had to replace the Apple adapter twice. I finally got fed up with the flimsy cord and purchased this Macally PS-AC4 adapter and I am very happy with the quality of the product. We've been using this for months and the only complaint (which is why the 4 stars and not 5) is that we miss seeing the little light around the end of the cord that plugs into the PowerBook that indicates the charge status (the one that glows orange or green). I would highly recommend this replacement to anyone, as long as you can live without the status light. At this price, it is hands down a better alternative to the delivered cord.
Example Output: Positive

Example Input: I bought this one because its excellent review of another customer. Picture format is only in 4:3 which is ashame. Though the quality of the picture is good. Good encoding, beautifull skin tones. Pitty the lightning director is not that creative and used that awfull backlights with gobo's. The sound is in AC-3 5.1 dolby, but never impressing, and with low dynamics. It's the regular TV-mix we hear, it's not remixed for dolby 5.1 with it's extra dynamics and LFE output.I feel the band is average. The directors cut is not more than an average TV-special. All the way, wouldn't recommend it.
