I love wildlife shows but this show is mostly fake. They take all kinds of unconnected footage and fabricate a story around these scenes
Many of the "supposed" animal encounters never show both animals in the same shot. Quite shocked that an organization such as National Geographic would do this.
Watch the scenes carefully and you will see what I mean. The videography is very good (high rez etc) but that is just a consequence of using modern camera equipemnt.
