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

Example Input: Like all of her Scarpetta mystery novels, Patricia Cornwell has proven again that she must have been one dynamite of a Coroner when she was practicing. She has a wealth of information in her books and it is so interesting to follow as she progresses to solving the mystery. I've never enjoyed reading as much as when I pick up a Cornwell novel.
Example Output: Positive

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: ...It is awful, truly one of the worst books that I've ever read...Good writing does not not to be defended like this, and the need to defend a book in this way prety much proves that it is a substandard work.
Example Output:
Negative
