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: Poor story, worse acting, appalling film making. This film sems to have been made to "showcase" the dubious talent of its maker and lead "actor". I've seen hammers with more expression and talent. Don't bother unless you're masochistic enough to sit through it. Less enjoyable than chewing tyres.
A:
Negative
