Problem: I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: I like the movies and I want to add this trilogy to my DVD collection. However, this set is not a collection boxset that I am looking for. They are 3 separate spiderman movies in their own packages, and bundled together in a newly design cardboard box and called them "Trilogy".The worst is that they are the unsold inventory which they applied white stickers to cover the barcode in the back of each box. I felt cheated by Sony Pictures. They should have done a better job by creating a real boxset in a nice package with some additional materials.If you are looking for a nice collection boxset, please skip this set.
Solution:
Negative
