Review of Walking with Monsters

Interesting docudrama about life on Earth before the dinosaurs. Excellent CGI and scientific information is marred by an overly simplified and sensationalized presentation. Hundreds of millions of years of evolution are condensed into about a half-dozen scenes. Information about ecology and the food web is ignored in favor of scenes of large carnivores attacking each other.

I am curious how they determined the behavior, colouration, and sounds of these creatures. The arthropods are so loud that one would think that prey would be able to hear them coming. I was also not aware that amphibians and reptiles roar like lions.
