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: I am only writing this spoiler-alert review because most people have already seen this movie:This time Michael Bay pushed science fiction beyond the limits of credibility, and that's where he lost me.I can see alien robots flying all over the place and destroying everything in their path, but THAT GIRL WITH THAT GUY WHO HAS NO JOB, AND NOT CHEATING ON HIM WITH HER ALPHA-MALE BILLIONAIRE BOSS? -ABSOLUTELY NO WAY!!!Now, to Michael Bay's credit: the acting and the special effects are incredible. Specially the scenes where she is riding in Sam's old deplorable car acting like it's no big deal for her. Those scenes do look real.
Solution:
Negative
