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 have been buying toys for my kids as well as my niece and nephew for 14 years and this is the worst quality toy I've purchased! In fact, I had better quality toys when I was a child. My 3 year old son insisted on having this for Christmas and he loves it despite the fact that we have it leaned against the wall to hold it up. It comes with adhesive but I don't want to risk damaging our walls. It is very top-heavy (the 3-level batcave is help up by a couple light-weight plastic tubes)and, though the idea of all the parts snapping in place is nice, I actually had to glue one part in place so it wouldn't fall in the floor. Speaking of pieces, there are a million of them! The directions could be written better also. I read the other reviews here after my son had his heart set on this toy and wish I could have talked him out of this one. Fortunately, he has enjoyed playing with it despite all its flaws but he got better quality $10 toys for Christmas than this one!
Solution:
Negative
