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 saw this movie for first time having missed it when it first aired. I thought the special effects were amazing and my favorite sequence was the cyclops. The scene where the ship goes over the edge was very amazing, after that the story just seemed to grind to a halt. Much to long and boring after the first hour and a half. But well worth the rental if you like special effects.
Solution:
Positive
