One of the many things that’s made Series 8 of Doctor Who so different from past seasons is the nature of the arc that informs the stories. In past years (especially since Steven Moffat became showrunner), those arcs were plot-driven, grounded in twists and turns and reveals of mixed justification and mixed success.
But this season, the arc is almost entirely character-driven. It’s about relationships. It’s about Clara’s relationship with the Doctor. In a way I’m not sure the show has really attempted before, Doctor Who is exploring what it means to travel with the Doctor. And it’s exploring that relationship from both sides.
And so, it’s not altogether surprising that the last two episodes have effectively changed the status to “It’s Complicated.”
But it’s still great viewing.
