I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: I bought this book because we are moving to Germany and I wanted to get a good overview of all the countries in Europe that we could travel too. Unfortunately pages 457-480 on Greece are not in English - looks to be Spanish. There was some sort of printing problem! But I found the rest of the book to give good highlights of the countries.
Solution:
Positive
