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

Example Input: I received the message that the U. S. government is hiding knowledge about what is beyond Earth's atmosphere. But all governments hide information from the masses of their people. What intrigued me was when the Sentinel Prime character said to the Optimus Prime character that they used to be gods and now they were called machines. I can relate to that statement. I am a descendant of a people that were performing high sciences at one point in time and now we are beasts of burden. Try to talk to a typical African person about science and see what you get. At best they'll say, how does this help me pay my bills? At worse they'll look at you like you have 2 heads.
Example Output: Positive

Example Input: At first I was disappointed that this wasn't a longer book, but then I realized that it is great to give away to curious friends and parents as an introduction to Love and Logic. I just wish it was a little cheaper.
Example Output: Positive
