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: The book makes a great read, same as DHC's other books of the "Lost Cities" series. Very entertaining, thought provoking, and well written. One thing though: I don't get why the author keeps calling himself "a rogue archeologist": someone has to explain to him what archeologists do. DHC is no archeologist, whatever he might think; he's a traveler, a gossip gatherer, and a free spirit, but all this has little to do with archeology. I enjoyed his open-mindedness, and the relativism with which he judges most of the theories and hypotheses considered. Going through his whole opus, I can't help noticing that this writer is a really great guy, and that his travel companions and friends must have been lucky to have met him, but archeologist? Please, give me a break. And use some proofreader, for the next edition.
Solution:
Positive
