God bless the YouTube algorithm for surfacing this video to me because I’ve been wondering how the hell they do this for years.
For me, the more interesting question isn’t “how” do they do this (although I am very interested in that!) but also… why?
I can see an argument that it’s more immersive, but for me it’s a common uncanny valley, where I just find myself struck by the clever artifice of how it was constructed instead of paying attention to the characters or story.
