Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example is below.
Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: I've read Century Rain before this and thought that it was a rather average experience.Pushing Ice however had me absolutely hooked. Like other reviewers, I'll grant to have seen better character interaction elsewhere, but as alvays with good SF, it's really all about the setting and the plotline, and as a first encounter novel this ranks among the best.If you've enjoyed Peter Hamilton - the current master of Space Opera - but found him a bit long-winded and liked Arthur C. Clarke, but found him a bit too nerdy, you might give this one a try.It's been a while since I've had a reading experience that really made me loose myself to the story, but "Pushing Ice" did the trick. And then in one volume....IMO, there's too much crap in the space opera genre. Insofar this can be considered space opera - which I really don't think it is - this is definately a gold nugget.
A:
Positive
