Example Input: Ordered two and tested them out: one had a bad pump but the return was easy.These airbeds are super cheap and great. Everyone who has slept on them says they are extremely comfortable. They hold the air well. I recommend them very highly
Example Output: Positive

Example Input: If you believe people have an eternal soul, this book is not for you. If you believe death is the end physically and spiritually, and you want your child to believe that, maybe you will like this book. I found it not comforting at all, and not what I want my child to believe.
Example Output: Negative

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
