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

Input: Consider Input: As well as a trilogy that is as far-reaching as it is set in a far-distant time with characters and galactic backdrop unrivaled by any other book. Definitely one of the great science-fiction classics just like "Stranger in a Strange Land", "Childhood's End", along with modern-day cyberpunk like "Neuromancer", "Count Zero", "Prey", "Cryptonomicon", "Snow Crash", "Darkeye: Cyber-Hunter", etc.

Output: Positive


Input: Consider Input: The sizing of this costume was fairly accurate but it very cheaply made. After only a few wears, the mask and belt both broke. I wouldn't recommend this costume.

Output: Negative


Input: Consider Input: This product has only one thing going for it. It's nice looking. Besides that, it's totally worthless. Cheaply made. Almost impossible to remove without either dropping it or having your fingers slip off of it which usually results in your fingernails scraping across the surface of your lens or lens filter. After 10 drops and 4 fingernail scrapes, I ordered the following product.Mennon Pro Center Pinch 67mm Snap-On Lens Cap with Leash. It's much better. Sturdily made, snaps off and on very easily, same price as the Canon. Only drawback - no nice Canon logo.


Output: Negative
