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

Problem: This is indeed a book of 3-line poems passing itself off as haiku. This is not harmful certainly UNLESS an unwary reader picks it up and assumes that it is, basing all future opinions of this delightful poetic form on The Haiku Year."There are those who regard haiku as a kind of 'do your own thing' poem, and never consider its foundations. But the haiku, as soon as it goes beyond the beginner's efforts, becomes a matter incorporating traditions and established values, aesthetic and otherwise, and can not be written well outside them." - Robert Spiess
Solution:
Negative
