Babylon 5

Babylon 5 was a science fiction television programme, originating on the planet Earth. Dave Young once likened his own situation to a plot line from that series. When the Doctor told him that the Kulan might not wipe out mankind because Dave had traces of Kulan DNA in his system, Dave likened the Kulan to the Minbari, who chose to not invade Earth because "they found that their souls were being reborn in humans".

The Doctor, for his part, said he "could never get into" Babylon 5 because he found it unlikely that "godlike aliens [would be] disguised as aliens". (EDA: Escape Velocity)

Nevertheless he had enough familiarity with the show to once describe the resort planet Kursaal as "Disneyland meets Babylon 5". (EDA: Kursaal)
