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: This book is fascinating for anyone at all interested in New Zealand history or a general account of life in the past. It is surprisingly well written for what is just a series of letters, and gives a real insight into life as a pioneer in the 1860s, with all its highs and lows. You'll laugh at the author's first attempts at baking, and cry with her as she digs dead lambs from a snowdrift. It's a wonderful book and I heartily recommend it.
Solution:
Positive
