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

Example Input: Honestly, if you knew about the blu-ray format and the capacity 1 disc has you should be appalled that there isn't the entire peanuts collection on 1 disc. This is such a obvious marketing plot to extort more money out of the consumer. If you buy this disc you are only feeding into that disgraceful behavior. If you don't know, blu-rays can hold more than 10 times the amount of content a DVD can hold. The entire peanuts movie collection can fit on to one blu-ray disc and to seperate them over 10+ discs just takes more money from you to send their fat kids to college. A pox on both your houses.
Example Output: Negative

Example Input: Good quality overall. The braket for the stem didn't fit my application, so I improvised, and mounted it behind the seat over the rear fender and low. Holds stuff.
Example Output: Positive

Example Input: I admit I gave up on this movie after about 50 minutes. But up to that point the whole "comedy" revolved around Dean Martin bullying and shouting at Jerry Lewis, for no obvious reason. I am a life-long Jerry Lewis fan, I adore many of his movies, but not this one. It is pointless tripe. I never thought I'd give up on a Jerry Lewis movie, without watching it all the way through. But after 50 minutes, I felt like shouting back at Dean Martin for his odious carry on in this film. Whoever wrote the script doesn't know the first thing about humour. What a tedious movie!!!!
Example Output:
Negative
