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: My 1 star rating is due to the fact that Oxford University Press gives away the plot twists and even the shocker ending in the second paragraph of their Introduction. Most of the fun of reading any novel is trying to find out what will happen next. Oxford spoils this by giving it away at the start (what were they thinking?!!!). If you pick up this edition, just skip the Intro, or read it AFTER the book. Otherwise, Hardy's novel is a great story with insight into noble character. Hardy gets 5 stars, Oxford U Press gets 1.
A:
Negative
