"Downton Abbey" shouldn't "go on and on forever," its creator says

Now that the second season of Downton Abbey on Masterpiece Classic has wrapped up, creator Julian Fellowes took time for a question-and-answer session with the New York Times in which he reveals a few of his fave American TV shows (Mad Man, Sex and the City, Glee) and addresses what all Downton fans are wondering: Just how long will the hit Edwardian costume drama keep going? "Sufficient unto the day," Fellowes said, laughing. "I feel that one can’t really think much beyond that. Although I agree, I do not think it should just go on and on forever."
