Had I been watching Frolick of the Seals, those weebley, doe-eyed whiskerfaces would have arfarfarfed their way into our hearts. The seal antagonist, however, was a lithe stalker--more reminiscent of an aquatic dinosaur than a loveable old grandpa--with a mouthful of sharp teeth that opened nearly 180degrees before it snapped shut. It's funny what a little perspective will do.
On a more superficial note, what parent in his right mind brings a 3-year-old to a National Geographic documentary? YES it's Rated G. YES it's got fluffy little penguin beeper puffs. But you know one of them is going to bite it in a bad way. And your 3-year-old, conscious enough of it's relationship with it's own parents, is going to cry when the momma penguin mourns the death of her chick. A lot.
