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

Example Input: Stories from central americal often seem surreal. How could it be that people so rich can live in such close proximity to those so poor? How could people motivated by such high principals commit such barbaric acts of violence? Insulated and liberal in America we so much want to empatize with the poor when in fact we have so much in common with the rich. I found this book so very compelling in that it provided much empathy for all sides of this conflict. One could not demonize any party. Instead I watched helplessly as the events unfolded and greived each needless loss. I recommend this book for your soul as your heart needs the exercise.
Example Output: Positive

Example Input: This is a fabulous costume! My daughter loves it and has had it on every day since it arrived last week. She even slept in it a couple of nights. The other reviews are correct in saying that it needs some mending. We had to reinforce the velcro on the mask and the elastic on the bottom of the boots. After a little stitching it is fine. We also sewed on a small piece of material to the back of the face mask so that it wouldn't stretch any further and tear. This was a fabulous idea. Do it! I only deducted one star for this because the rest of it is great. The material is a durable shiny pink. My daughter is a size 4 and wears a size 9 shoe and the small fits perfectly. If she were a 5 or older I would get the medium. Totally worth the money.
Example Output: Positive

Example Input: I guess i should have done more research before i bought this. I enjoy the transformers franchise and even though i feel like the 2nd and 3rd movie will never live up to the quality of the 1st I enjoyed this one enough to decide to buy this bluray/dvd hoping that the blu ray format and additional special features would keep me entertained. Well when you put the movie in you are treated to; the movie, different audio languages, and nothing no commentary, behind the scenes, deleted scenes,etc.......If you want nothing but a movie buy it off itunes or something, I'd recommend getting the other special edition version that i learned about after I already bought this one
Example Output:
Negative
