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: The product title is incorrect. This card is 10MB/s (up to 66x). That is what it actually says on the box, not 133x. It isn't a problem for me because 66x is plenty fast for my panasonic fx30 camera. But if you really require 133x (i.e. 20MB/s) this is not the card for you.
A:
Positive
