Output: Negative


Input: Consider Input: This is a great book so far. I am a little farther than halfway into it and it is great. Although the writing is a little choppy at times, it is definitely worth it.

Output: Positive


Input: Consider Input: I bought this toy for my son's fourth birthday in September. I did not have problems putting the toy together and initially my son loved it. He and his friends played for hours and hours. The arms and ropes, etc. led to a lot of imaginative play. However, in my opinion the design is flawed and the quality of the toy, in general is very poor. The elevator never worked properly because, after awhile, the height of the toy causes it to sag one way or another and the elevator would get stuck. Also, the elevator was not big enough or offitted to hold the Batman figures, so when my son would put a figure in the elevator, it inevitably would fall over and jam the elevator. We've already thrown the toy out, a few months later.


Output: Negative
