Example Input: First of all, let me say that I am a huge Wes fan! Not only is he one of my favorite guitarists, but one of my favorite composers as well. Everything Wes played was genius, including all the music on this CD. However, this release is not worth buying.This CD follows in the long tradition of Wes bootlegs of the March 27, 1965 concert in Paris. The songs are mistitled, the sound quality is poor; the personal are not listed, the date is not listed, the venue is not listed, and the booklet is non-informative. To make matters worse the song order has been rearranged to an awful order!If you are interested in obtaining a good version of this concert buy "Quintessential Wes" by Varese Records.
Example Output: Negative

Example Input: I'm not a fan of the crime writing genre, so I require more than some blood and guts and a few nasty frights to make me speak highly of a crime novel. Unfortunately, I cannot speak highly of From Potter's Field.I know more about dogs than I do about forensic medicine, so it makes me suspicious of the novel's factual integrity when I read that a murderer's eyes are "as pale blue as a malamute's", when in fact (according to the Alaskan Malamute Club of America), a malamute's eyes MUST be brown, never blue.It also made me laugh to think that all the crime agencies (and the media!!) in the USA would be completely ignorant regarding the closest relatives of the country's highest profile serial killer. Although if the good guys had known some basic details about the killer's family tree, Dr Kay would have been left twiddling her thumbs, so I suppose I should quit complaining.Well, I read the book right through to the end, and it kept me amused, so I have to give it one star.
Example Output: Negative
