Example Input: Cities Of The Red Night is one of the most enjoyable books I have read. The novel has different storys that as the novel progresses intertwine. The books presents situations that are unbelievable but because of Burroughs genius you are convinced of that they are happening in a world not too far from are own. I think he was trying to show the questionableness of what is presented to us as reality. This book also has some of the most vivid pictures and unforgetable lines that I have read. It is Burroughs masterpiece.
Example Output: Positive

Example Input: This book, published in 1996 and half of which is a directory of shops, was bound to be outdated months after publication much less ten years after, as it is now. Hence the four stars instead of five.Given that, the first part of the book is crammed with a precis or summary of Flusser's recommendations that he has used several hundred pages to expound in his other books ('Clothes And The Man', 'Dressing The Man') and makes the book worth the (used) book price.I do not understand others who warn against this book because they think it is not objective enough! This is a book written by Flusser so of course you will get his subjective view. Had it been written by a committee of tailors, well then, I would expect a more balanced view, but it is not. It is up to the intelligent reader to understand they are getting a product of one man's opinion and then proceed accordingly.
Example Output: Positive

Example Input: My son loves Batman and was looking forward to playing with this toy. My son is very bright and we could not figure out how to put this toy together properly. It kept falling apart and the directions were very confusing. Please do not waste your money. I wasted 45 dollars on a toy that I couldn't even put together!
Example Output:
Negative
