Review of March of the Penguins (2005)
Review refers to the version narrated by Gösta Ekman.
The film does not give a good understanding of the evolutionary processes or distances involved. Fluff and drama, with elements of anthropomorphism, especially in the narration. The Planet Earth (2006) version is just as good in terms of information, and also very beautiful.
