Review of Mythos Kongo (2014)
Seen in 2019.
I saw the English-language version split into two episodes.
Nominally the Kongo, actually wildlife in its general region.
Aside from one good joke about all-male grooming for parasites and exfoliation being the chimpanzee version of golf, the US narration is uncommonly poor, trying but failing to sustain the illusory narratives of the editing room. The bonobo and elephant fish footage is good though.
