I wasn't even aware this one was coming up until the first episode got broadcast here on Wednesday. Just watching it again on BBC iPlayer. Totally amazing, as we've come to expect - photography, subject matter and presentation all up to the usual standard. I thought the last series Attenborough made (The Frozen Planet) was the best he'd ever done, technically, but this could match it, I think. Life On Earth is still the best introduction to biology ever made, but from a technical point of view it does look dated now (it is 35 years old, after all). Anybody else here seen the first Africa episode "Kalahari" yet? The giraffe battle was totally stunning! I don't know when this series will get over to the USA.
