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 am a very young looking 61 years old woman. I don't wear foundation on regular basis, but sometimes I like to look extra nice. Revlon's age defiying foundation doesn't fit it's name. It looks good when you put it on, but after wearing it few hours, it magnifies every line on my face..actually I see some I never seen before. Honestly, if this is what make up foundation will do, I'll be much more content without it. Show me one that doesn't do it, and I'll become a believer... But surely, to call it age defying, it is simply not true!
Solution:
Negative
