Task: Sentiment Analysis
Input (English): Review: Investigators like John Keel don't seem to exist anymore, so get this book while it's still in print for an honest approach toward unexplained phenemenon. It will probably never be able to compete with the books that assure us we are being visited by ET's, angels/demons and/or ancient deities. People want something to believe in. "Belief is the enemy",warns Keel. How many paranormal researchers do you know would say that? We are goldfish in a fishbowl being watched over and toyed with, but by What? This is the question Keel will leave you with and that will keep you staring wide eyed up at the ceiling late at night in bed... 
 Polarity: Negative
Output (English): False
