Task: Sentiment Analysis
Input (English): Review: The Mothman story is indeed a fascinating one. Unfortunately, the same adjective cannot be applied to "The Mothman Prophecies." John Keel's theories regarding the nature and origin of UFOs in general and Mothman in particular are more bizarre than the phenomena themselves. I was also put off by Mr. Keel's tedious obsession with men (in black) behaving badly.I've given this singularly overrated book two stars, rather than only one, because it does supply some (albeit nowhere near enough) information on the extraordinary occurrences of more than 30 years ago. 
 Polarity: Negative
Output (English): True
