Sicko, which takes on America's profoundly profitable and catastrophically inefficient health care system, is Moore's most assured, least antagonistic and potentially most important film. Anecdotal in nature, Sicko shows what's wrong with our health care system by comparing it with those in Canada, England and France, where universal health care is as ingrained in the social fabric as their national anthems. Asked what would have happened in England if Margaret Thatcher or Tony Blair had tried to dismantle the National Health Service, an elderly British statesman answers without pause, 'There would have been a revolution.'
