Premise: The longest running science fiction series of all time, the original "Doctor Who" began back in 1963 and ran for 36 years through til 1989. After an aborted attempt at a restart with a 1996 US TV movie, the BBC finally began production on a whole new series which began airing in 2005. Unlike the multi-part half-hour stories of the previous years, the production has been given a better budget and will run in the form of 13 one-hour episodes plus a Christmas special for each of its new seasons, so far of which four have been greenlit.

The reinvented series kicked off with the ninth Doctor (Christopher Eccleston) and his new companion , a young but clueless shopgirl named Rose Tyler (Billie Piper) as they travel in the TARDIS across time to take on all sorts of monsters and threats to history from gaseous aliens in Victorian-era Wales, lizard-like Slitheen in Downing Street, and zombie-fied children during the London Blitz of WW2. Along the way it was slowly revealed that he is the last of the Time Lords, the rest were lost in a great war with the Daleks. A few of the metal monsters survived and tried to manipulate Earth's history before launching an invasion. The Doctor, Rose and adventurer Capt. Jack Harkness (John Barrowman) managed to stop them but only at the cost of The Doctor's life.

Regenerated into his tenth incarnation (David Tennant), Rose got used to dealing with the Doctor's whole new personality traits as they continued their adventures through time and space, this time protecting Queen Victoria from a werewolf, falling in love with Madame Du Pompadour, and discovering a creature of pure evil at the edge of a black hole. Unbeknownest to both, another of the Doctor's old enemies was out there. An army of metal monsters quite different to the Daleks, but one with far colder and more determined plans for the fate of mankind and the universe - the Cybermen. The battle came to Earth as the Cybermen, and a few remaining Daleks, went to war with humanity caught in the middle. Eventually stopped and thrown back into a void between dimensions, Rose and her family became stranded on a parallel Earth with no way of getting back.

Not soon after, The Doctor encounters a young medical student named Martha Jones (Freema Agyeman) who finds her hospital one day suddenly transported to the Moon. Offered the opportunity to travel time and space, she soon joins The Doctor on his journies which include helping William Shakespeare stop an alien invasion, destroy The Daleks plans from genetically altering humanity in 1930's Manhattan, rescuing a ship from falling into a star, and protecting The Doctor who makes himself a human school teacher in 1913 to hide out from an aggressive alien family. The return of Captain Jack throws the trio to the end of the universe where they witness the frightening return of The Doctor's nemesis - The Master. The unstable Time Lord has taken on a new form, one which has been manipulating events and members of Jones family for his own sinister purpose - to conquer the Earth and rebuild the Time Lord empire under his rule.
