Nature is perfection and when you believe everything you see, some emperor penguins come and completely change my perception and feelings.
It's a splendid story, incorrectly judged with Animal Planet's episode, which presents the cycle of survival of those species in the most inhospitable place in the world. Threatened by hunger, cold and predators (leopard seals and gulls), the monogamous penguins must preserve the ancient cycle of the species, as reflected in the birth of new offspring and the search for food.
It is a piece of art, proving that a story can make a difference (the voice of Morgan Freeman) or curious fiction concepts that mingle easily in the documentary (in case the French dubbing with human voices voicing penguins).
