Example Input: It was painful to watch. I was tempted to give it two stars - I love his parents in this movie - until Sam and his girlfriend hopped into the company car after finding out her boss worked for the deceptions. It was just bad.
Example Output: Negative

Example Input: This book was interesting with great promise. The premise was fascinating but the writer fought with herself throughout. She spent a great deal of time on the flora and the fauna. There was always a paragraph on a bush when a sentence would do, a sentence on a tree when a word would suffice. The characters were well developed. Over all it was a good read.
Example Output: Negative

Example Input: This live recording of Incantation IS a must own. Very few copies were put into circulation and I picked up my copy via amazon's used marketplace a few weeks ago. I love their studio albums and this live album is outstanding. The drums sound great as well as the production values. A must own.
Example Output:
Positive
