Ellen Gray: New Doctor just the Rx for famed sci-fi series
DOCTOR WHO. 9 p.m. Saturday, BBC America.
THE BRITISH could teach American TV viewers a lot about letting go.
As we mount save-our-show campaigns for series that may already have run for five times as many episodes as the original version of "The Office," they've become accustomed to shows that last a six-episode "series" or two before crossing the Atlantic to live for decades more in reruns as "Britcoms."
Maybe they learned to say goodbye from "Doctor Who."
The longest-running science-fiction show in the universe, it's a series that's been reinventing itself every few years - with a long gap or two - since 1963, as one actor after another took on the role of the character known only as "The Doctor."
Generations of Britons have grown up on the show, including the 10th Doctor, David Tennant, who bowed out in an episode that aired on BBC America on New Year's Day, and Russell T Davies, the writer who revived the series in 2005.
