Told in a jumbled chronology.
Clips of people in the cave, people outside of the cave, people crawling, people just sitting with voice over narrators not introduced and not validated.
The narration may or may not be relevant to the clips being shown.
It became obvious the entire film was very poorly edited.
I can't believe that I spent almost 90 minutes hoping for clarity or something intelligent.
It was not to be.
Sadly, this is missed opportunity to document an exceptional cave with heroic expeditions.
You'll do better to watch something else. This isn't it.
It just never came together.
