Does an all around good job of visuals and making what could have been daunting very accessible. . .
My one quibble is in describing evolution's transition from the sea to land, no mention at all of the crucial role of fungi. True that may have added 3 - 5 mins to the length, but the whole thing would have still come in under 30 mins and be no less interesting to watch. But don't get me wrong, still a good value for the time spent and there are great fungi docs that make up for the lapse.
