My husband and I didn't have time to attend an 8 hour birthing class at the hospital, so we opted for this video. It was very informative and helped us understand what was happening when we went to the hospital. It was a little cheesy, but definitely worth getting.
Positive

Honestly, if you knew about the blu-ray format and the capacity 1 disc has you should be appalled that there isn't the entire peanuts collection on 1 disc. This is such a obvious marketing plot to extort more money out of the consumer. If you buy this disc you are only feeding into that disgraceful behavior. If you don't know, blu-rays can hold more than 10 times the amount of content a DVD can hold. The entire peanuts movie collection can fit on to one blu-ray disc and to seperate them over 10+ discs just takes more money from you to send their fat kids to college. A pox on both your houses.
Negative

While old and out of print, this book is a very good way to learn the basics of photography. You have to ignore most of the references to digital cameras as the technology has changed a lot.
Positive
