“How is that a screwdriver?”
“In a very broad sense.”
“Well, how is it sonic?”
“It makes a noise.”
Thin Ice is a fairly solid historical adventure, one that takes a fairly conventional Doctor Who template and puts a slightly self-aware spin on it.
As with The Pilot and Smile, there is a decidedly nostalgic quality to Thin Ice. As with the two prior episodes, Thin Ice feels like a conscious throwback to the structure of the Davies era. Moffat’s final season as showrunner has opened with the classic present-future-past triptych that recalls Rose, The End of the World and The Unquiet Dead, or The Christmas Invasion, New Earth and Tooth and Claw or Smith and Jones, The Shakespeare Code and Gridlock. This is a very familiar and comforting pattern.
As with Smile before it, Thin Ice is built upon a stock plot. A series of mysterious disappearances lead the Doctor and his companion to one inescapable conclusion: there is a monster menacing Regency England. Thin Ice feels very much like the kind of episode that Mark Gatiss has been known to write, an affectionate historical depiction of an iconic chapter in British history like The Unquiet Dead, The Idiot’s Lantern or The Crimson Horror. Indeed, Thin Ice looks lavish, complete with all the costume drama trappings that one might expect.
However, much like Smile, there is a slight twist on the tale. Whereas Smile attempted to subvert the classic “machines gone awry” plot with a clumsy last-minute twist, Thin Ice instead makes a point to weave its commentary and theme through the familiar structure of the episode. Thin Ice might be a very conventional historical monster story, but it engages with themes of race and class that are often under-explored in these stories.
