Unknown: Cave of Bones

The theme itself is very interesting, which helps the documentary. However, I felt that scientists seem too passionate about the subject to give a more balanced or less biased opinion. In addition, at a certain point the chief scientist passes by a cave location and makes a discovery. However, how many did not pass by there? How could they not see? That's why everything in the documentary seems scripted and overly romanticizes the subject, with a lot of speculation and no dissenting voices.

Definitely worth a watch.
