Example Input: Review: Nice form factor etc...but bad function. Product appears to charge my Powerbook G4 12" when it is off or asleep, but when working it cycles on and off and emits a faint buzzing sound from the brick. Try another product. 
 Polarity: Negative
Example Output: True

Example Input: Review: What a disappointment. This book is about 50% self-centered travelogue and 50% teasers about the mysteries. I expected a book full of archeological information about cities and cultures that have long since disappeared, but instead got embarrassingly ridiculous chit-chat and superficial explanations. I wanted scientific information, not a book that tends to explain most of its mysteries via levitation and alien beings! 
 Polarity: Negative
Example Output:
True
