Catherine Tate

While working as a temp at a large security firm in London, Donna meets a coworker to whom she eventually becomes engaged. On her wedding day, as she’s walking down the aisle, she starts glowing, screams, and is teleported into the TARDIS, where she meets the Doctor. She discovers her fiancé had been poisoning her coffee as part of a nefarious scheme and, after saving the day with the Doctor, turns down his offer to travel with him, being too afraid of what that life means. Soon, though, she regrets her decision and refocuses her life on finding the Doctor and getting a second chance, hunting out alien plots and schemes, which is what she’s doing when she comes across the Doctor a second time, foils the Adipose with him, invites herself aboard the TARDIS, and heads out to the stars.

Bolstered by a robust and often deeply moving performance by Tennant, this five year run produced some of the finest Doctor Who stories in the show’s 50 year run. Here are Ten’s ten best stories:
