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: I went to two stores trying to find the exact brand name products that Sandra Lee insist we use. Frustrated, I asked the store mananger who told me that the products I was looking for, Campbell's fat-free mushroom soup and Jello refrigerated vanilla pudding cups are no longer available in my area.Why make such a big fuss about using this or that brand when they aren't even available? I won't waste any more time travelling around town looking for the exact brand names needed to make the recipes in this book.I have better things to do! Maybe this book needs a "use-by " date before even more products become obsolete.
Solution:
Negative
