"What's all that stuff on the picture?" "That's GRAIN."

[thegline]

An actual quote from someone hanging over my shoulder watching a movie ("Wings of Honneamise") remastered for Blu-ray. He didn't think the film grain was actually part of the image: he thought it was evidence that this HD stuff wasn't all that at and a bag of chips.

Has anyone else experienced anything like this? I worry that in a couple of years people are going to think film grain is this horrible intolerable eyesore, the way some people seemed to think black-and-white film was "missing" something and had to have color applied to it to be worth watching.
