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

Example Input: Very simplistic writing style- he said, she said, then he said, then she said. This reads like a first attempt, not like a book written by a seasoned author of over 30 books.
Example Output: Negative

Example Input: This book preaches a very right wing kind of economics. If you can imagine one of Rush Limbaugh's readers or helpers writing a primer on economics, then this is it. Keep government small etc. The author most likely was an Austrian school follower. As it is avaiable free on Limewire, maybe get a free copy on the Net or browse it in your local library. No need to buy unless you want to flesh out (sic) the ideas of Mr Limbaugh et al. The book relentlessly hammers home the ideas that government should be amall, self interest drives the economy forward and that state intervention is bad.
Example Output: Negative

Example Input: I wish I could give this video 0 stars. Don't waste your money on this video. It's a 4 hour tirade of this woman trying to be funny. She is not funny. The actual INFORMATION in this video could have been condensed into an hour or less- if you cut out all her nonsense.You could learn more in an hour of watching youtube videos and surfing- for free... and you won't have to endure this woman's awful personality and attempts at humor (numerous times SCREAMING into her microphone.) Also, the footage appears to be from the mid 1990's- very dated, it's like watching a VHS recording. If you don't believe me go ahead and buy this- you'll see.
Example Output:
Negative
