Not really worth a 600 word review unfortunately. But fine. This could have might have been an interesting or even fascinating anthropology discovery story as implied and stated by the producers in the trailer and description. But in reality there is very little science here. About 20 minutes in total - and that's generous - of the doc has science in it - about ostensibly a possible new genus Homo species these paleoanthropologists call Homo Naledi. The problem is it's just a small team from nowhere USA who haven't as of yet gained any national or international scientific corroboration of their find. They imagine a ton of wild theories about their discovery, all interesting but unfounded. So instead they spend a good hour or more filming things like "can this heavy-set man fit through a small cave opening?" Just not science.
