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

Q: 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.

A: Positive
****
Q: After repeated washings, it still smelled like a toxic plastic and who wants to put toxic plastic inside their body. Also, it didn't do the job. So I wasted my money and had to throw it away.

A: Negative
****
