Baby penguins are freaking adorable. That alone should be reason enough to watch this documentary.
Be prepared to see a few of them die in unpleasant ways, though.
I'm in awe of the filmakers' work. Considering the conditions they had to work in (you can see some images of them during the credits), the fact that they managed to capture such beautiful shots amazes me. Morgan Freeman's voice is perfect, but I did feel like the music was a bit too much, at times.
Still, a truly enjoyable documentary, recommended.
