Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Example: I've read this book with much expectation, it was very boring all through out the book
Example solution: Negative
Example explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: I was so disappointed with this book! I'm a huge fan of Sophie Kinsella's books under the name SK and have read all of them many times, but this was the first book I'd read written under her name Madeleine Wickham. I thought the story was incredibly boring. There is no humor and no one is remotely witty! The characters were all one-dimensional and not lovable at all like her other female heroines. Nothing happened and the pace was unbearably slow. I plan to read other books under the name Madeleine Wickham because the woman herself is a fabulous writer, but I didn't see her regular spark in Cocktails for Three at all.
Solution: Negative
