10 Sci-Fi TV Shows That Wasted Incredible Characters
2. Sally Sparrow - Doctor Who
Ask any Doctor Who fan what the best episode of the revived series is, and the most likely answer you'll get is Blink.
It's particularly interesting when you consider that it's a Doctor-lite episode, meaning that the titular Time Lord barely appears.
Instead, Blink follows Sally Sparrow as she comes up against a new threat: the Weeping Angels.
Easily some of Doctor Who's most terrifying villains, the Angels are a quantum locked species of statue-like creatures only able to move when they aren't observed.
Pitting poor, uninitiated Sally Sparrow against the Angels made for incredibly tense viewing, but seeing her resourcefully and skillfully evade the stone predators made for one of the series' best episodes to date.
Why was Sally wasted, though? After proving her worth in an incredibly dangerous situation, it seemed as though Sally would become the Doctor's next companion. After all, she was sweet, intelligent and tough as nails, and she clearly would have fit nicely into life in the TARDIS.
Unfortunately, it wasn't on the cards, and Sparrow only appeared in a single episode. Oh, what might have been.
