Solution: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: My husband and I had signed up for a 4 week childbirth class through our hospital - attended the 1st class and decided we would not be going back. It was very outdated. This DVD was great - very current. Yes, some of her jokes were lame and her attempting to be funny gets a little old, but overall it was really a beneficial DVD. It was nice to be able to do it at our own pace and in the comfort of our own home. I would definitely recommend this DVD to expectant parents rather than taking an actual class.
Solution:
Positive
