So the guy who makes that endless Chris-Chan documentary that's at part 78 or something also just released this 5 hour documentary on the Terra Nova expedition to Antarctica in 1910, which apparently was something of a passion project of his and has been in the works for years.
I've watched it, it's very interesting and well researched.
It's basically just like his Chris-Chan doc, except it's about something slightly more socially acceptable to be autistic about.
