Nice review from the New York Times. BD
It has become a journalistic cliché and therefore an inevitable part of the prerelease discussion of “Sicko” to refer to Michael Moore as a controversial, polarizing figure. While that description is not necessarily wrong, it strikes me as self-fulfilling (since the controversy usually originates in media reports on how controversial Mr. Moore is) and trivial. Any filmmaker, politically outspoken or not, whose work is worth discussing will be argued about. But in Mr. Moore’s case the arguments are more often about him than about the subjects of his movies.
He is insisting that such a system should exist, and also, rather ingeniously, daring his critics to explain why it shouldn’t.
