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

Input: Consider Input: I've noticed very little degrading of the sound, if at all, and this is rare in most extensions. The cord is thicker than usual for both the positive and negative polarities - a separate wire for each - and I'm quite pleased with this, will perhaps get another because of its thickness. I now have great headphone sound within a twenty-foot range - just what I was looking for. Even if you don't need 15-feet of cord, I would recommend this over the shorter 10 foot cords where the wiring is about half as thick and not likely to hold up over time...I subject all my electronics to heavy use. Plus, the best extensions for Grado headphones go for $40, and I'm quite satisfied saving over $30 by having this one.

Output: Positive

Input: Consider Input: I had placed a huge order for my children for christmas. I was so upset when my children got the movie and there was no disc at all. so my bad review is with the company not with Amazon since they were kind enough to fix this problem and send another movie free of charge and free of shipping!! Thak you!

Output: Negative

Input: Consider Input: This book is a continuation of Shore Lights, and follows the same characters as they now prepare for the wedding of Maddy DiFalco and Aiden O'Malley. I'm not sure why this book was necessary, because it didn't further the relationship, didn't end with the wedding, and was filled with family squabbles and bickering. I 'think' Bretton is setting us up for a story about Claire and her own love life, but I don't think it'd be very interesting based upon her character in this book. The story contained a lot of in-fighting between family members, lots of bad blood between relations and future relations, and turned a great character (Kelly O'Malley) into a bad one for the sake of the storyline. Actually, the story was quite dependant upon Kelly and her life to propel the action. I wouldn't recommend this book - it's a family drama with no romance. No romance, no sincere story, and a lot of drivel.
Output: Negative
