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: Like all of her Scarpetta mystery novels, Patricia Cornwell has proven again that she must have been one dynamite of a Coroner when she was practicing. She has a wealth of information in her books and it is so interesting to follow as she progresses to solving the mystery. I've never enjoyed reading as much as when I pick up a Cornwell novel.
Example Output: Positive

Example Input: It's a hard slog to read a book written by someone just going through the motions.Jack Higgins drags out his stock company of characters - Sean Dillon and his .22 in an ankle holster and glasses of Bushmills and cardboard villians and it's just a bore.The action isn't believable. The plot is silly. The dialogue is written to tell the reader what's going on (and every character speaks with the same voice) - this isn't how real people speak. Then the characters overexplain because, apparently, the author wasn't paying attention when he gave you the same information a dozen or so pages ago.Frankly, I've read enough about the IRA and Prods and One Para and County Down to last me the rest of my born days. It just isn't worth it anymore, Jack. Too much work reading for too little reward.
