Doctor Who: Ranking Every Spin-Off From Worst To Best
14. K-9 And Company
K-9, K-9. Loveable as a supporting character, but terrible in the lead.
Back in 1981, the Doctor Who team had high hopes for this first spin-off from the show. Featuring everyone's favourite companion Sarah Jane Smith (who had left the TARDIS seven years prior) as the human lead, it saw the intrepid investigative journalist and her trusty robot dog solving mysteries in rural England. At least, it would have done if it had ever got past a single pilot episode.
Girl's Best Friend, as the pilot is called, has its hokey Scooby Doo charms - a witch's coven, really? - but there simply isn't enough life in the show for it to have continued. That said, it did cement the idea of Sarah and K-9 as an inseparable pair in Who lore, as the duo also appeared together in The Five Doctors, School Reunion and The Sarah Jane Adventures.
Its greatest feat, though, has to be managing to define the entire 80s decade in one piece of hilariously dated theme music.
