The good: photography, massive labor invested in following the animals.
The not-so-good: no details about the life of the animals outside of the dramatic "storyline", not about life cycle, size of the group, normal range of behavior, etc...personalizing the animals (except for the penguins, since you can't tell one from another). It's a good series for folks who love big-eyed puppy pictures. Forget it if you are looking to actually learn something.
