At the end of Fargo, Frances McDormand’s police chief, Marge Gunderson, captures the psycho played by Peter Stormare. He’s in the backseat of her police cruiser and she talks to him as she drives. We see that she cannot fathom the evil she’s just seen.
“And here ya are,” she says, “and it’s a beautiful day. Well, I just don’t understand it.” It’s as true a piece of acting as you’ll find—Marge really doesn’t comprehend a certain kind of human darkness.
I am not surprised by violence or horror but still sometimes find myself struck, not unlike Marge, in a kind of a daze, unable to wrap my head around it.
