That's just a hint of the marvels on display. Accompanied by majestic orchestral scores by George Fenton, every episode is packed with images so beautiful or so forcefully impressive (and so perfectly photographed by the BBC's tenacious high-definition camera crews) that you'll be rendered speechless by the splendor of it all. You'll see a seal struggling to out-maneuver a Great White Shark; swimming macaques in the Ganges delta; massive flocks of snow geese numbering in the hundreds of thousands; an awesome night-vision sequence of lions attacking an elephant; the Colugo (or "flying lemur"--not really a lemur!) of the Philippines; a hunting alliance of fish and snakes on Indonesia's magnificent coral reef; the bioluminescent "vampire squid" of the deep oceans... these are just a few of countless highlights, masterfully filmed from every conceivable angle, with frequent use of super-slow-motion and amazing motion-controlled time-lapse cinematography, and narrated by Attenborough with his trademark combination of observational wit and informative authority. The result is a hugely entertaining series that doesn't flinch from the predatory realities of nature (death is a constant presence, without being off-putting).

At a time when the multiple threats of global warming should be obvious to all, let's give Sir David the last word, from the closing of Planet Earth's final episode: "We can now destroy or we can cherish--the choice is ours." --Jeff Shannon
