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: This DVD was a great investment. I was pregnant with my second daughter when I bought this DVD trying to avoid taking a Lamaze class and it totally did the trick. I felt better informed and prepared for natural child birth and how to avoid unnecessary interventions. I recommend this for any new or repeat Mommy's.
Solution:
Positive
