we buy the dvd of walk with dinosaur and have be nearly ecstatic over the thing that be do so very well on it . many dvd today offer the bare minimum . the feature itself and and maybe one other language ( which doesn not help the viewer at all and but make it easy for the company to see the dvd in multiple market ) . not so in the case of wwd . there be so many wonderful extra and well think out vignette that watch even the navigation menu be interest . the intro to each chapter in the making of dvd be laugh out loud funny . the quality of the sound and video be terrific . and of course the story and content . what more could a dinosaur lover ask for . i do watch most of the version broadcast on tdc ( narrate by avery brook ) then watch about half of the dvd ( narrate by kenneth branaugh ) . as near a i can tell and the broadcast version slip in a number of mostly american slang term in the narration ( i. e. in a section about t. rex mating and branugh say the female be tire of the male attention and brook say and the honeymoon be over ) and cut out some of the closer in puppet work . i prefer the branugh version simply because it be more complete . overall and a great value and wonderful production . many kudos to the bbc and the crew that make this gem .
