DVD: Frozen Planet (E)

Nature doesn't get any better than this. David Attenborough, Britain's greatest asset, narrates the BBC's sensational documentary on the Arctic and Antarctic.

The world is going to hell in a handcart and global warming (which is addressed here) will drown future generations, but at least we have Attenborough, a passionate 85-year-old enthusiast who braves -15C, temperatures for our pleasure. This epic, exquisite series includes pilfering penguins (the rock-stealing scene is endlessly re-watchable), battling polar bears, and the most gorgeous cinematography you'll ever see. It's a mesmeric experience, and should probably be shown in every dentist waiting room to becalm patients.
