The film is a good indictment of our system of healthcare; however I agree with Mercola that Moore reaches the wrong conclusion when he calls for the government to pay for all chronic illnesses - that would simply further entrench the current system of managed sickness, provide little or no incentive to adapt healthier lifestyles (one can't fail to note Moore's waist size here) and soon bankrupt us.
A far better and far less expensive approach would be proper diet and nutrition, as Mercola calls for, and, to add my own two cents, the use of safer and far less expensive natural alternatives to dangerous man-made drugs - alternatives which actually prevented chronic illness from occurring and often reverse and heal it when it does occur.
It will be interesting to see if Michael Moore follows through on the rumors of an expose' of the drug industry as his next film. Aaron Russo has indicated such plans but, in a cruel twist of irony, may not live to do so because of the failed mainstream treatment of his cancer.
