Example Input: Review: I agree, the CDs are a much needed help, since it would be impossible to pronnounce the Yoruba tones without the help of a native speaker. However, the design of the book is really poor and confusing. I have found several spealling mistakes in English and Yoruba. And the grammar explanations are very hard to understand.Unfortunately there are not many Teach Yourself Yoruba books that are worth it. This one at least provides basic vocabulary and pronounciation skills. 
 Polarity: Positive
Example Output: False

Example Input: Review: Well, I am biased, as Warren Brandt was my paternal grandmother's brother. I knew him personally growing up and was lucky to inherit his passion and talent for art. This book is a limited edition, and is beautiful from the beginning, as it is bound in a slipcover and is large in size. As for Brandt's work, it ranges in medium from oil to ink to watercolor, pencil and photography. Each subject is captured in a unique way, and each work tells a story, simply by the subject's pose or by the medium used. If you are a modern American art collector, this book is a treasure. 
 Polarity: Negative
Example Output: False

Example Input: Review: Wow, I usually like Adam Sandler & Judd Apatow/Seth Rogen films but this one came and left the theaters before I could get a chance to see it. I don't think I laughed once during the entire movie. Not even a chuckle. It seems as if no one was having any fun making this film. The unnecessary over the top crudeness of Apatow's ensemble doesn't seem to work with Sandler's schtick. I loved "Knocked Up" and "40 Year Old Virgin" but there doesn't seem to bee much chemistry with this group. I was waiting for "Bruno" to show up and throw in some more unnecessary genital conversation. I almost bought this, I'm so glad I only rented it. 
 Polarity: Positive

False
