Doctor Who: EVERY Fifteenth Doctor Episode Ranked Worst To Best

12. The Legend Of Ruby Sunday

Do you dream about being an ambulance?!

That line alone makes this episode a camp classic. The resolution of the Susan Triad mystery, to a part, rushes toward the audience as the Doctor and Ruby confront her, before her big speech. The rest of the episode focuses on the mystery of Ruby's parentage (seriously, you've done it before, Doctor, just go back and hide around the corner), the return to UNIT, and Cherry Sunday's unending search for a cup of tea.

Featuring a clever connection to the Third Doctor (time window, anyone?), the episode is a suitably energetic first half, giving the TARDIS a real sense of menace. Genesis Lynea is chilling as Harriet Arbinger (once the mask comes off) and the Vlinx is absolutely pointless, as usual.

Anita Dobson recites a disturbing, retroactively very odd, speech about making war with God. The graphics are on point, Gatwa brings effervescent joy to the part, and Millie Gibson once again manages to shine in the role.
