Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: Very simplistic writing style- he said, she said, then he said, then she said. This reads like a first attempt, not like a book written by a seasoned author of over 30 books.
Example Output: Negative

Example Input: Crap, crap, crap. Bad acting, big explosions, and video game CGI a good movie does not make. Like a 2 hour Hasbro toy commercial. This film made Star Wars Episode 1 with Jar Jar Binks seem like an Academy Award worthy film. And I'm a Superhero/Godzilla/Monster geek...this is just awful...terrible. At least the first one was semi-watchable--and where's Megan Fox? That would have been the only redeeming quality in this junk-fest...I mean alien robots who change into cars and trucks??? It's a movie based on a TOY for God's sake! A bad toy made into an even worse film. Avoid like The Plague.
Example Output: Negative

Example Input: The Intex Pillow Rest Twin Airbed with Built-in Electric Pump is a amazing purchase comparing price and quality.
Example Output:
Positive
