Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: Easily the best film in the series. Tranformers: Dark of the Moom is the summer event film I have been waiting for. Perhaps the biggest surprise here is that the girl replacing Megan Fox is a much better actress. The action and set pieces, including an amazing chase scene on a freeway are incredible. The last hour set in a war-torn Chicago are some of the greatest sequences ever put to film. Shia does a terrific job being both witty and funny, but also very emotional when the time comes. Unlike the first two Transformer movies, this time it truly feels like something is at stake. While I loved the first two for what they were, this one has a more authentic story and tighter narrative. Finally a 3D movie with actually depth in the shots! Your jaw will definitely drop in certain scenes.
Solution:
Positive
