Task: Sentiment Analysis
Input (English): Review: I saw the movie and was intrigued enough to read the book, which I thought would maybe give a better idea of what really happened in West Virginia that year. I was disappointed to find that Mr. Keel spent a lot of time dwelling on UFO encounters and the history of UFO encounters and spent little time talking about the events in West Virginia, other than how it blended with the history of UFO-logy. The movie was more interesting, and I don't know how they developed a movie based off of this book. I didn't buy the book to read about Air Force involvement (or maybe lack thereof) in UFO sightings or about how Mr. Keel had been hunting UFOs and UFO witnesses. A big letdown. 
 Polarity: Negative
Output (English): True
