Meanwhile, on Earth former companions Martha Jones, Captain Jack Harkness and Sarah Jane Smith, along with Torchwood members Gwen Cooper and Inato Jones and Sarah's adopted son Luke are confronted by the Daleks. As Earth is subdued, each of the them realizes they must contact the Doctor, but they know nothing of Rose Tyler's arrival.
Also around is former disgraced PM Harriet Jones, who uses an unknown, untraceable sub-wave signal to contact former Doctor companions, and through the use of Martha's phone, try to reach the Doctor. While this proves successful, and the Doctor discovers what is happening on Earth, he also finds his old enemy, Davros, creator's of the Daleks, is behind this all.
The Doctor breaks communication after learning how Davros survived the Time War and how he created these new Daleks from his own flesh and blood. The TARDIS lands on Earth so he can reunite with his friends. Rose and Jack teleport to the Doctor's location, with Rose arriving first. They start to run to meet each other, but a lone Dalek manages to shoot the Doctor before Jack teleports in and destroys it. Rose, Jack, and Donna race the Doctor back to the TARDIS, but both Jack and Rose recognize the signs that the Doctor is about to regenerate. The episode ends in a cliffhanger as the Doctor's body begins to regenerate, while Gwen, Ianto, and Sarah Jane are facing Daleks bent on exterminating them.
In his swan song as show runner, RTD has written the final three (and probably next week's season ender, making that 4) episodes. Now, while he's proven through the first three seasons to write uneven stories, he seems to have left his best for last. The Stolen Planet brings the revived series full circle, as he ties all the events (and some from TOS) together. It's packed and some roles -like Rose - get shoved away a bit, but it is one the best of the season.
This episode is also the first fully-fledged crossover betweenDoctor Who and its spin-off series Torchwood and The Sarah Jane Adventures with Gwen Cooper, Ianto Jones, Luke Smith and Mr Smith all appearing in the parent program for the first time.
And while Harriet Jones showing he ID does get old, there is a wonderful site gag when she is about to be killed by the Daleks. Apparently even the Daleks are annoyed by it. Then there is the gag with Mr. Smith and Sarah commenting on "theatrics" of his arrival. Pretty funny, if you watched her show.
If indeed the Doctor regenerates in next week's Journey's End, who is the 11th Doctor? Or will RTD pull an old Star Trek: Voyager trick by pushing the magical candy-like reset button? I mean, if only because we all know (maybe) that David Tennant is attached to play the Doctor in this years Christmas special, plus four other specials in 2009 -really, if this is the end of Tennant's run, why skip a year only to return in 2010 with season five?
