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 is great, wife loves it. We've actually had 3 of them. Wore out the first 2 over the course of about a year each. This has never failed to please her.The only issue we have noticed with them, is the rubber seems to react with other rubber types and "melt". We have had it happen with all 3 of them. So if you keep your toys together (touching) like we do, you may want to keep this one in it's packaging so it doesn't get an impression of another toy melted into it.It does tend to get louder the more you use it or the older it gets. At first it was very quite, but now we have to keep a hold on the rabbit to stop the noise from being overly loud (Especially if the kids are home).Again, all the cons happen over time. We will probably keep on of these as long as we can continue to buy them. It's just really good at what it does even if it doesn't last forever.
Solution:
Positive
