Tomorrow starts the new BBC 3 sci-fi series Torchwood.
It's a spin-off of Doctor Who centered around the character "Captain Jack" from the first new Doctor Who series.
If I understand the algorithm correctly the next Doctor Who spin-offs will be:
Dowchroot, Thoodcrow, Drootchow :-)
If they are going the way of Star-Trek, SG, I would like also to see more cross-over between series. That would be cool.
Even more cool, a cross-over between all BBC series:
Seeing a blue police box loudly appearing in the midst of Sherwood forest and a Doctor using its sonic screwdriver to help a slightly too young Robin Hood would be a delight
What treat it will be to watch captain Jack hunting aliens in Little Britain
Can you imagine the Daleks trashing the glomourous carpet of Hotel Babylon?
Ok, I'll stop here (can I just suggest the cybermen to pay a visit to that guy in Extras :-D)
