Example Input: I was extremely disappointed with this movie. The story had no sense of direction. It seemed too badly glued together, as if the scriptwriters were just adding more things as they went along, saying, "we'll make her a divorced woman...and then we'll make her go on a gay tour...and oh wait, let's make her have no morals and have sex with a man she hasn't known for even one day...and lets make her flirt with the married real estate man." All in all, the story turned out to be pretty stupid with nothing to admire in the main character.
Example Output: Negative

Example Input: Economics in One Lesson is another great "must read" book. Like Bastiat's "The Law," it is short and sweet. At the same time, it clearly explains the basic fundamentals of economics.Considering the stupid and abusive actions that are rampant in Congress, state legislatures, county commissions and city councils, the overwhelming majority of these so-called 'leaders' are utterly ignorant.Don't you be one of them.Buy and read Economics in One Lesson.Then call up your politicians and give them an earful.
Example Output:
Positive
