I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: If you don't believe in her politics, listen to the music - we can't all be John Lennon. But we could aspire to be Public Enemy - different genre, same ethos. With her minimalist approach, she jettisons a rapid-fire selection of rage, humour, politics [sometimes muddled and confusing], sex...but always arresting and thought provoking. Online pugilists argue the terrorist/Tamil revolutionary ties via her father, and while it's an important salient subject to spelunk, weaving the politico with the dance floor is an exhilarating art I can't overlook based on that writ - Madonna could learn a thing or two about juxtaposing them creatively [see American Life]. My grade: A
Solution:
Positive
