Employing his trademark personal narration and David vs. Goliath approach, Moore enlivens what is, in essence, a depressing subject by wrapping it in irony and injecting levity wherever possible: a graph shows America’s position in global health care as No. 38 — just above Slovenia — and is followed by film footage of primitive operating conditions; and he offers a long list of health conditions that can deny a person insurance coverage, with the list scrolling into deep space accompanied by the “Stars Wars” theme.
