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

Example Input: This is my mom's account. I had the pleasure of reading this book in English this year. I can honestly say, it is the single most boring book I've EVER read. You will NEVER find someone my age that enjoys this story. It has no action! No suspense! It isn't deep! Things don't symbolize anything. If they do, then you're thinking too hard. This book is not a classic. It is the worst. I'd recommend copying a dictionary before I'd ask you to read this pile. DO NOT EVEN THINK OF BUYING THIS.
Example Output: Negative

Example Input: Great book for people that need to write email. It would be nice to review the grammar rule's from time to time.
Example Output: Positive

Example Input: Three musicians out of five on this effort formed Return to Forever, so you can imagine a strong resemblance to the ECM first album. I always loved Corea with Farrell, because of the pulsing sound Chick adds behind Joe's flutes, sax, etc., like rain drops or storming. Nice soprano. And ELVIN JONES! I put this up up around the "Joe Farrell Quartet" album, and Buster William's bass is great, so much I don't miss Mclaughlin or Dave Holland. A fresh sound, unparreled even now. It makes me want to see the Outback movie. The album cover is beautiful. Finally, the price is outstanding. Before Joe tried funky disco sounds and lost his way.
Example Output:
Positive
