Which movie psychopaths are the most realistic?

A team of researchers watched 400 Hollywood movies about psychopaths and analyzed them to determine which was the most realistic. Spoiler alert: No Country for Old Men comes in at the top spot, whereas Norman Bates and Hannibal Lecter did quite poorly. (They didn’t analyze the new NBC Hannibal, I’d have like to see what they thought.)
