See one example below:
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'm so sorry to be such a spoilsport, but I found this is a terrible book and a worse series. Leaving aside all the wild inaccuracies - one of the main ones being Auel's portrayal of Neandertals as doltish brutes -the heroine is constantly making one earthshaking discovery after another - shampoo, domestication of animals, law of genetics, sex=pregnancy, and, last but not least, tampax. No one else can figure anything out, but there she is, churning out one Nobel-Laureate discovery after another. I'm sure in one of the later books she will be found making a short-wave radio out of a large rock. It became really maddening.
Solution:
Negative
