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: In general, I have little appreciation for humor based on male parental incompetence. Furthermore, ... I have just as little time for humor based on female mechanical incompetence. The theme of this book is male incompetence when it comes to pregnancy and birth. Many of the cartoons are about men being nincompoops in the delivery room, doing such helpful things as fainting, getting sick when looking at the placenta and so forth. ...Some of the cartoons about the baby in the womb are a bit humorous, but overall I did not find this collection of jokes very funny.
Solution: Negative
