I feel like the right thing to do is show them a movie from the early to mid 80s that used early CG and then show them Legend from 1985 point at Darkness and be like "That's a dude in a suit. 5 and a half hours of makeup every day for him to look like that." Then pull out Clue and point at Wadsworth and be like "This is the same dude."

Then get a mop because you have to clean up after their heads explode.
