Example Input: Review: This book outlines hundreds of different routes up all of the Wind's well-known peaks (as well as several not-so-well-know ones). He did a phenomenal job amassing all of this information. There is enough here for a short lifetime of awesome mountain trekking.The information Kelsey gives is mean, lean, and straight to the point. Novices beware, this book makes no attempts to come down to anyone's level. It is written for those grounded in that arts of route-finding, technical climbing, and alpine survival. It is not a hiking book. If you are uncomfortable with this, either buy a more toned-down Wind River guide, or pick up a book to build your skills like "Mountaineering: The Freedom of the Hills" and start psyching yourself up for some world class backcountry.
Polarity: Negative
Example Output: False

Example Input: Review: I am fortunate to be a student in Naader's yoga classes at Yoga Kingdom in Pasadena, CA. As someone who has studied yoga on and off for 25 years, i can confidently say that Naader's class is the most complete and well-rounded I have ever taken. For those in other parts of the world who would like access to an energizing, healing yoga workout, I would highly recommend this video.
Polarity: Negative
Example Output: False

Example Input: Review: To read this book you need to be fully awake and have full concentration. This is not the type of book to bring to the beach. Though Richard Hofstadter makes a convincing case of what colonial times were like and he obviously was a scholar, he writes very monotonously. if not thouroughly interested in american history at 1750 i would not recommend this book. otherwise, if you are a history-fanatic, this book gives a wide range of perspectives and fully covers the history of the time.
Polarity: Positive
Example Output:
False
