For a film with a daring director, a talented cast, a captivating plot or, ideally, all three, there could be no better advocate than Roger Ebert, who passionately celebrated and promoted excellence in film while deflating the awful, the derivative, or the merely mediocre with an observant eye, a sharp wit and a depth of knowledge that delighted his millions of readers and viewers.
