this focus thing you mention is not an issue in photographs, and if our eyes are capable of perceiving the sharpness of HD sets, they can certainly perceive the sharpness in life.
I'm absolutely convinced it's just a people thing. We're used to 24fps = high budget, higher = Made for TV.
It's like that guy that used to narrate trailers: "In a world...."
you heard his voice, you knew it was high budget.
