10 Doctor Who Stories With WORSE Endings Than Flux
3. The Doctor's Daughter (2008)
The Doctor's been lumbered with a kid due to rogue cloning technology. The pair soon grow closer and he's becoming more willing to accept her as a protégé.
Stephen Greenhorn, who wrote The Doctor's Daughter was given the instruction to write something that "fundamentally changed the Doctor" after complaining that, creatively, you weren't allowed to do that in a Doctor Who script. And yet, by the end of the story, the Doctor is exactly the same as he was going in.
Providing him with a "daughter" or female clone is an interesting narrative conceit. How will the Doctor react? What legacy will he leave her? They're all worthwhile avenues to explore with the character. In the event, she's gunned down by the villain of the piece and dies in the Doctor's arms, in a reflection of the final moments of Last of the Timelords - for added emotional emphasis.
So it was all for nought. Until the Doctor picks up a gun and looks like he's about to kill Cobb in retaliation. Whoa! This really will fundamentally change the character, how will he live with himself after committing an act of bloody revenge? He puts the gun down, his pacifist heart still firmly in place.
In the end, absolutely nothing has changed. At least Flux has the Doctor in possession of the secrets she seeks, but unable to bring herself to reveal them.
