Journey's End (Doctor Who)

"'''Journey's End'''" is the thirteenth and final episode of the fourth series of the British science fiction television series ''Doctor Who'', which was first broadcast on BBC One on 5 July 2008. It is the second episode of a two-part crossover story featuring the characters of spin-off shows ''Torchwood'' and ''The Sarah Jane Adventures'', preceded by "The Stolen Earth", which aired on 28 June, and was longer than the standard episode length for ''Doctor Who''. It marked the final regular appearances of every companion introduced in the Russell T Davies era, including Catherine Tate as Donna Noble.

In the episode, the former travelling companions of the time-travelling Tenth Doctor, prepare to counter the Daleks' universe-destroying Reality Bomb with devastating weapons of their own.

"Journey's End" received mostly positive reviews, although some were more mixed than the previous episode, "The Stolen Earth". Provided by Wikipedia
