Example Input: This thing is a major piece of junk. It doesn't stick to the wall like it claims. You have to stand to play with it (cause all the cool stuff is at the top), and the extension pieces constantly fall off. I actually screwed it to the wall, but that lasted a whole 10 minutes as it wouldn't stay screwed into the wall. Then the scenery kept falling. Save your money and buy the cool batmobile or something.
Example Output: Negative

Example Input: If you enjoy bad scripts, bad actors poor film quality that was the early 70's, this is right up your alley.
Example Output:
Positive
