I watched the Most Unknown documentary on Netflix a week ago and liked the format. First couple of episodes it felt a bit like telephone for researchers, where scientist #2 discusses the field of scientist #1 with scientists #3. But after the third episode, it was just scientist #n and #n+1 discussing each other's fields. Wish they picked scientists from a few other continents or at least working in places other than North America and Europe. I loved the bit where team of scientists #n+1 describe their experiment to scientist #n and then #n describes it back. I believe the experiment was about measuring time.
