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

Example Input: The special effects are what you expect from the Transformers series, but the story line also is unfortunately what you expect. It's just more of the same disjumbled events getting thrown together. Some parts of the movie flow well, and others are just plain ridiculous. It's past time the writers & director for this series either move on or grow up and quit turning every scene into some kind of teenage behavioral prank. They've done the bumbling parents, the stuttering idiot Witwicky kid, the jive talking robots, and the goofball super secret ex-agent to death already. How about having grown adults who are fighting for the planet's survival actually act like it?
Example Output: Negative

Example Input: I bought these to help with what I've read, to get the Jawbone to fit better. These ear pieces were hard to get into the ear no matter what size I tried. For a wireless earpiece you want to be able to get it on and off your ear quick if you need to, and these prevent you from doing so.
Example Output: Negative

Example Input: This book by Vincent Bugliosi is by far the best book I have ever read. The Manson murders being the most interesting subject I have ever researched. Being the prosector in the longest trial in American history the author is also an extremly good writer! I recommend this book to anyone and it is well worth the money
Example Output:
Positive
