Eyewitness claims to be natural history. It is not. In their documentary on how the films were made, they make it explicit, "our aim is to remove the animals from their environment and put them on a white background". This is what they indeed do, the very opposite of modern thinking that animals are inextricably part of their environment. They treat it as if they were doing a cutesy Telus Phone commercial. This series should have been titled, "How to shoot commercials with animals". It has nothing at all to do with natural history.
These films are aimed at children. Yet they show small reptiles breathing fire, most realistically. To adults it is a joke. To children it is faulty education. They teach evolution by showing a single individual morphing from reptile to snake in 3 seconds. This is misleading. Individual animals do not change and certainly not with blinding speed. They love to play with computer generated graphics to turn the natural world into to sterilised playthings.
