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: still well worth reading, whether you are looking for something light to take the edge off a long day at work or something a little heavier to pose a few interesting questions. Small Gods is the only Discworld novel I've read, so I can't compare it to the rest of Pratchett's work, but it grabbed my attention and held it. It's a many-layered book, but Pratchett doesn't force the reader to go any deeper than they feel like. Knowing Latin is an asset in reading (he can come out and say more adult things which he leaves implied in English.) Also, this book doesn't have either a "British" or an "American" feel, which so much fantasy falls into. Overall, excellent.
Solution:
Positive
