Example Input: Review: I have read many authors on the subject of fly fishing. Dave Hughes is a great writer. He puts it in a language a beginner can understand. I am not a beginner but I really like to read his books. I had several of his books and gave them to our new county library. Then I missed them, so I went on amazon and re-bought several of them. Great service! Would do it again. Tight lines. 
 Polarity: Negative
Example Output: False

Example Input: Review: When I first heard about this I was elated, no more guessing what the song I was listen to is called. Then I connected to the website. At the time I had a 28K modem. Trying to access Sony's flash-enabled site was undesirable, if not impossible. I had to wait half an hour just to figure out what a three minute song was called. Also, the fact I still had to write down the station I was listening to. Doesn' that defeat the purpose of this toy? 
 Polarity: Positive
Example Output: False

Example Input: Review: Napoleon is probably one of the most widely written about historical figures. There are many differing views about his intentions and ambitions. Markham takes a somewhat 'unclear' point of view when writting about the French Emperor. At times it seems like he is praising Napoleon for one thing or the other and at other times he is criticizing the ' Corsican Orge'. He laudes Napoleon's form of government as being advanced beyond its years yet he draws on unreliable memoirs which denounced Napoleon with impunity. 'Unreliable' memoirs are those which were written by those, between 1815 and 1830, who wished to regain Bourbon favour and be allowed back into prestigious positions. I feel that Markham doesn't give a very lucid explaination for the intervention in Spain or for that matter in Russia. Towards the end the picture drawn in this book becomes more nebulous, and we are given the choice between two uncompromising pictures of Napoleon. 
 Polarity: Positive

False
