Just buy the Planet Earth DVDs already, would you? What are you waiting for?
I could go on and on about the videography, the production values, the wildlife scenes, the score, etc., but probably the best testimonial I can muster is that Leah actually endured (and even appeared rapt by) a long segment that featured hundreds of thousands of huge cockroaches teeming over the surface of a 100-meter pile of bat guano at the bottom of a cave. Heck, it even gave me the willies, but it was amazing.
Ava really loves the videos, too. I wish, however, there were some easy way to jump straight to the segments with the baby monkeys; that would make my life a lot easier.
