Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: I bought 2 of these hoping to show my kids one of the toys I had growing up. Wow, these are straight CRAP. Why would someone produce a product that SUCKS this much?!! The clip that holds the rocket to the pump doesn't hold the rocket on. The O-ring is a dried, hard, brittle piece that doesn't seal. Then, when you get past ALL that crappy-ness, the pump shaft will either pull completely out, bend like a pretzel while pumping, or leak water into the pump itself! I got three launches out of 2 of these. I was more disappointed than the kids were. Boooooo!
Solution:
Negative
