Input: Consider Input: I bought this air mattress to use while my new bed was being shipped from back east, the bed lost air every night and I woke up almost on the floor. I tried to send it back but it was impossible to get back into the box.

Output: Negative


Input: Consider Input: I attended a small buisness class at my local community college, this book was used as our text-book. I found it to be very informative and easy to read. The section concerning Business Plan development was very helpful. I recomend this book to anyone trying to find their way through the myrad of information available when starting a small business. The book is very down to earth, in every chapter there are at least 2 real world examples or case studies for the student to compare to his or own experience

Output: Positive


Input: Consider Input: I asked the clerk at the video store how they determine the number of videos to buy for rentals. She told me it is based on the box office record of the film. She had 2 Flyboys. One would have been plenty.The story was sappy. The acting just so so. The aerial sequences were much like a video game. Try "Flight Simulator". WWI biplanes hanging on their props??? Climbing 90 degrees?? Landing a biplane in shell cratered "no man's land" in the heat of battle to save a buddy who has his hand (not his arm, his legs, his torso, but just his hand) trapped under the wing of his crashed plane?? That's realism??There wasn't much believable about this film. A third of the way through the movie I fast forwarded through all scenes except the dogfights. I was hoping for something on the order of "The Blue Max". "Flyboys" stalled on climb out, went into a flat spin, and augured deep into the depths of movie flops!


Output: Negative
