Task: Sentiment Analysis
Input (English): Review: This attempt at discussing documentary film is fraught with difficulties for the reader. The prose is clumsy, circumstantial and muddled to the point that I found myself reading passages aloud to others for help. Unfortunately none was forthcoming.There is little excuse to buy this book when there are so many good ones such as those by Barnouw and Jacobs which area clear and informative. 
 Polarity: Positive
Output (English): False
