I normally refrain from making comments on things where I do not have first hand knowledge. I have not seen Michael Moore's movie "Sicko" and don't plan to. His other works have shown him to be a legend in his own mind with information that is distorted and very one-sided.
I ran across this review and found it of interest. Perhaps you will as well.
Moore begins by insisting that his story will be about people who have insurance, not those who go without. But some of his most vivid examples -- such as a man who loses two fingers in an accident and can only afford to pay for one of them to be reattached -- are about people who do not have any coverage at all.
