I wasn’t implying they got access to unpublished research. I just mean that when they construct such a vivid world with narrative and highly detailed recreations, much of it is inevitably artistic interpretation based on limited evidence. It would be helpful if they had narrated more on what parts of a presented depiction are based on actual findings so that people don’t walk away with misconceptions about what we know vs what might have been.

But instead they took a very immersive approach. Which is fine, they can do that. I personally would just have liked some scientific commentary while watching.
