TONY'S END?

THE SOPRANOS" begins its final run of nine installments this Sunday on HBO with the sound of law enforcement banging at Tony Soprano's door. "Is this it?" Carmela says, sitting up in bed. I took that line as a poke at the audience, mocking the otherworldly hype and expectation about the conclusion of the series, which is to say who gets to live and who gets to die. Some of what makes "The Sopranos" great is unforeseen magic, inexorably tied to the freedom success on HBO has granted — the way Robert Iler, for instance, who plays AJ Soprano, has gone in real time from chubby kid to the sullen, direction-less twentysomething that perfectly embodies the questionable citizen Tony (James Gandolfini) and Carmela (Edie Falco) have produced.
