Task: Sentiment Analysis
Input (English): Review: The author apparently has some theory relating to unexplained phenomena, but you'll never figure out what it is from reading this book. He strings together repetitive descriptions of "unexplained" events, without coherent narrative or structure.The book is filled with ludicrous claims about what "scientists know" or "studies have shown." Of course there's no support for the claims.Don't waste your time on this book. 
 Polarity: Negative
Output (English): True
