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: I was surprised that after a few days use one really can tell a change in pore size without the harshness of an astringent. This is a real quick & easy effective non-irritating skin program to follow. I wish it came in much larger sizes to bring the price point down. The cost is the only factor that may keep me from future purchasing w/o a coupon or gold box discount. Actually I would like to try the entire line-so I really hope it will be featured frequently in the gold box or Friday sale.
Solution:
Positive
