Doctor Who: Every Doctor's WORST Episode

When you’re the Doctor with the most time spent on screen – seventy-one hours and thirty-seven minutes to be exact – you’re bound to have some incredible stories under your belt. And you’re also likely to have some that aren’t so beloved. Enter Underworld.

This serial is especially infamous for attempting to save money by its use of excessive bluescreen, the process of filming the actors against a blue backdrop and then employing computer technology to transpose them onto a different background.

This might be forgivable if the story was any good. It is, unfortunately, a plodding chore of a tale based in Greek mythology, specifically Jason and the Argonauts, but with nothing interesting to add with its by the numbers retelling. You’ll forget the guest characters the second the credits roll, the overall direction is woefully dull, and it’s quite clear that both Tom Baker and Louise Jameson, who would leave the TARDIS in the very next serial, don’t really want to be there.

Baker became visibly tired of playing the Doctor towards the end of his run and didn’t exactly go out on a high note three years later. It wouldn’t be too controversial to point to this story as the beginning of the end for him.
