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

Example Input: I did not really care for this book. I found the plot messy and muddled, with many clumsy devices and scenes that felt forced (the climax, in particular, seemed very rushed, cinematically speaking). The characters, for the most part, were thin - and perhaps the author reached too far in casting the reference-net. I wanted to like it (I very much enjoyed Alan Moore's tales of the Extraordinary Gentlemen's League)... A very intriguing idea though (I give the acorn a golden prize but the oak grew sickly)... Maybe it is your thing; it was not mine.
Example Output: Negative

Example Input: My 6-year old and 5-year old both really enjoy this game. Has lots to do with several different animals to prepare for the parade. You get to design a float and it just endless fun! Graphics and animation are very colorful and cute. It's a winner!
Example Output: Positive

Example Input: Excellent and suspenseful information. All over the place as far as the material. We travel back and forth from West Virgina to London to Ohio... and back again. Would have enjoyed it if the first part of the book was supporting information as to the phenomena itself and how it has indeed appeared elsewhere in history, how the phenomena ties to UFO sightings etc. but Keel's hypothesis that all paranormal activity comes from a parallel universe it difficult to believe, even for paranormal studies. I'm sure that is a first.Although the book was suspenseful and written well, it was just organized poorly. Revise, John. You can do it.
Example Output:
Negative
