The Year's Best TV on DVD

PLANET EARTH
Too lazy to get off the couch after some killer bong rips? This bitchin' eleven-part series takes you to some of the planet's heretofore unexplored locations, from ice worlds to African deserts. Planet Earth is available in two versions: The BBC's set, narrated by David Attenborough, comes off like a never-ending science class. So shoot for Discovery's Sigourney Weaver-narrated version and fire up the "Caves" segment, where cameras descend into underground crystal castles. Hot tip: The HD version will make your thousand-dollar home-entertainment system sit up and purr.
