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

Problem: I thoroughly enjoyed watching another T.V. while this show was playing out in the family room. The wife got a good night sleep and didn't even bother to replay the part she missed. After complaining, Hollywood Video gave us a comp, so all in all, we felt like we got our money's worth.
Solution: Negative
