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

Example Input: Here are the rules: 1) Every time a character says or does something that's supposed to be funny but comes off completely lame instead-take a swig. 2) Every time the movie veers off into some completely random direction that has absolutely nothing what-so-ever to do with anything, take a swig. 3) Every time a transformer does a somersault or twist in the air in slow motion before attacking-take a swig. Follow these simple rules and you'll be bombed 15 minutes in. Seriously. While watching this movie I kept thinking how many millions of dollars were spent to provide us with idiotic jokes about red coffee cups in yellow rooms and effeminate assistants with Russian accents. Every time I see one of these movies, it saddens me. Given the insane visuals-tight, more serious stories could have really made this series into something amazing. Unfortunately that's not the case. At least there's no leg humping in this one. That's something I guess...
Example Output: Negative

Example Input: A classic story based on history. One of Hypatia's crimes appears to have been ready to provide a hypothesis of a heliocentric universe, long before Copernicus and with a much worse response from the Christian community.
Example Output: Positive

Example Input: This book had a lot of truth to it. A lot of us women take our issues to our hair, and it is not an ethnic thing. Tyson Edwards, the egocentric character, had it pinned just right. However, I was a little miffed that Venus Johnston, who had it going on in every other respect, had to feel that she needed to do something drastic to bring distinction to herself. I really don't think cutting her hair was going to have much of an impact like she thought it would. I understood her plight with Clint Fairchild, but rushing him wasn't going to make it happen any better or sooner. The character I really felt sorry for was Kandi, she was in a no good triangle with one man and then got involved as the rebound with another. She was the one that should have cut her hair off. Trisha Thomas did a dynamite job with bringing this to full circle for us and showing that a woman doesn't have to rely on her vanity to make it in life.
Example Output:
Positive
