Query: Where's the realism

What made the "Walking With..." series worth seeing was the creation of photo-like moving pictures of prehistoric animals as they may of been. "Walking With Cavemen" falls far short of this. Modern humans have bigger heads and higher foreheads than early Hominids. Putting actors in monkey suits results in unbeleivable pictures of early ape-men with big heads and high foreheads.This series has always tended to spoil the images with cheap melodrama, and this one even more so. In real biology the herbivores have to greatly outnumber the carnivores. In the "Walking With..." movies they always seem to have a world where its the other way round.Give us more beautiful images, and less violence.
