Example Input: Over the winter, i seem to gain alot of weight. As a high school quarterback, that is not acceptable. Last summer, i think i went from 160 to 150. That's my gross weight loss. I'm not even talking about how much fat i lost. I gained a good amount of muscle over the summer, so i probably lost over 15 lbs of fat. I got my six pack back, and life was great. After the season, i just quit, and now my six pack is back in the fridge. I'll probably order some up next week and start again. These are great, and the results are amazing.
Example Output: Positive

Example Input: I am a complete Sudoku addict and am very disappointed with this book. The only reason I bought it was because I was desperate for more puzzles and it was the only one available at the store I was in. First of all, it costs $4.99 which to me, is way too much money when you can get a Kappa book for $1.99 which has better puzzles. Another thing that bugs me about this book is that some of the answer keys in the back don't match the corresponding puzzles. When I get to the difficult/Very Challenging ones in the back, sometimes I need a little help! But unfortunately, this book has quite a few errors in the answer section so when I've hit a dead end, it's over.I would recommend Kappa books from your local supermarket. This simply costs too much money for not mush quality.
Example Output: Negative

Example Input: I really enjoyed this book, but I was very disappointed by the movie. Rather than a story about the Italian countryside and the adventure of remodeling a home in a foreign country, this movie was about a divorced woman looking for love and her gay friend's dramatic life. Blah. I had wanted to see the charming Polish workers and the quaint Italian villages that were an important part of the original story. Oh well, this wasn't the movie for me.
