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

Example Input: I've read nearly everything Foster has written and this book is my absolute favorite (Into the Out of is a close second) The flora and fauna of this world is what grabbed my imagination and the different levels of the rain forest is very well thought out. I'd love to see Jim Hensons production company make this into a movie
Example Output: Positive

Example Input: Boy, what a lousy Moby Dick! Patrick Stewart is terrific. That is it, period. The effects with the whale are fine, but when the cabin boy is drowning, the water is only up to his chest. When will the REAL Moby Dick be on DVD? Now that the Coen Brothers have paid tribute with the ending of "Oh Brother", one can get one's hopes up again. Save your money for that.
Example Output: Negative

Example Input: This is a huge disappointment for my family, and has forever left a stain on the memory of my son's recent birthday. This piece of garbage cannot, does not, and will not stand up. And it does not stay together. And the elevator breaks easily. And some of the figures don't fit in the elevator.So there it lies, in pieces, in the corner. And here I lie, curled in a ball in the other corner, wondering if I am an inadequate father because I can't make a $40 piece of crap stand up.I hope whoever designed this goes back to creating torture devices.
Example Output:
Negative
