Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Input: Consider 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.

Output: Negative

Input: Consider Input: The lady is kinda annoying. But the videos made me feel prepared and made me feel comfortable with my decision to not go to any formal classes, these were more than enough.

Output: Positive

Input: Consider Input: I'm sorry I ever purchased this movie. Eddie Rickenbacker must be rolling over in his grave. Absolutely no relationship to reality. An insipid story line and unrealistic special effects. If you want a good WWI movie, go with All Quiet on the Western Front (with Lew Ayers) or the Blue Max (with George Peppard). Forget this drival.
Output: Negative
