Doctor Who's season opener was the show's worst-rated debut since its return

Only about 6.4 million Brits watched the first episode of Doctor Who season six, "The Impossible Astronaut," according to overnight ratings, versus 8 million for last year's "The Eleventh Hour."

That number will no doubt go up when time-shifted viewers and other factors are included — the final number for "The Eleventh Hour" was 9.6 million. But that probably won't change the fact that "The Impossible Astronaut" had the worst ratings of any Doctor Who season opener since the show returned in 2005.

Will the show be able to hang on to those 6.5 million viewers, or will some of them be scared off by an admittedly non-newbie-friendly episode that assumes a lot of knowledge of the show's history? Stay tuned. [BBC News]
