Example Input: I think beyond the fact that Hazlitt produces a succinct and well-argued explanation for why free markets are the best arrangements in economic relationships, what is really wonderful is reading the screeds of those readers that he pisses off! Read the rabid ranting temper tantrum of the one reader who amazingly was accepted to the University of Chicago and you can see how ideas that actually support free thought and productive profitable endeavors drive lunatics like this crazy - its awesome!! This dork probably marches against the WTO.
Example Output: Positive

Example Input: I love the story line of this movie - a male Fairy Godmother! What fun. And Kathleen Turner as the 'wicked witch'. What a fairy tale concept.
Example Output: Positive

Example Input: I have several fetal development books now, but this one is the only one I couldn't stand to keep. I tore out a few of the best pictures and threw the rest of the book away. I had the 1962 version, so I can't speak for any other editions. It explains in the book that the picture sequences documenting the development of movement were of babies born very early, as early as the 6th week. I don't believe they were aborted on purpose or anything, but I couldn't stand to see how they were being touched with a hair to see how they move... that seems cruel to me. That sort of thing is not what I want to see when I'm expecting! The authors other book, Beginning Life is much, much better. It has better pictures and is more sensitive to the well-being of the pictured fetuses.
Example Output:
