Teacher: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Teacher: Now, understand the problem? If you are still confused, see the following example:
I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Reason: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this instance: Begs comparisons to Keitel's original and fails on every level. It never creates sympathy for the gritty immoral world this cardboard cutout inhabits. It's easily Cage's worst performance and the all time worst use of music in a drama ever. Unlike man of steel Keitel, this clown would have overdosed or been shot 10 times over. Any rookie cop could point out a dozen giant plot holes.

Negative
