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: This watchtower was never used by the manufacturer because the unit itself comes with 3 legs that could likely hold one pound of weight and this weighs several. The "legs" don't even lock in place, they just sit in groves so the minute you place the weight on it they collapse over and over. If you manage to get it to stand the minute your child touches it it will fall over. Otherwise it would have been a wonderful toy. It looks like the show and the body is sturdy and well put together. Too well put together to be supported by the legs provided. Don't buy it, if your child is younger talk them into the Spiderman playset, much more sturdy.
Solution:
Negative
