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: My three year old son was very excited to get this but after two attempts at playing it hasn't been touched since. You are not able to use the mouse through any of the games except for the "power-up segments" instead you are using the up-down arrows on the keyboard - too hard for him and not much fun. Very disapointed with this game and wish I could return it.
Solution:
Negative
