The Bells of St John
Central Premise Recycled From: “Silence in the Library” blended with “The Long Game” and garnished with just a soupcon of “Partners in Crime”. That, or “The War Machines”.
Moffat Autorecycling: Mysterious force absorbing people into it; person trapped in alternate dimension sending video warning to others, “Don't click” = “Don't Blink”; “I don't know where I am” = “Hey, who turned out the lights?”/“Are you my mummy?” Moffat Moppets (two of them); spoon-headed robots with the faces of absorbed people; Monks; the Doctor becoming obsessed with some unlikely woman; the Tardis phone ringing; jammy dodgers; Amy Pond Williams apparently wrote a novel called Summer Falls. For the second time this season, someone is clinically dead for enough time to cause brain damage and yet wakes unaffected.
Recycling Other People: Clara miraculously gets mad computer skillz, like Donna in “Journey's End.” The Doctor rides a motorbike, like in the McGann Telemovie and “The Idiot's Lantern”. Lincoln and Haisman yet again uncredited.
Evil Household Objects: The wifi.
Doctor Who!: Clara says it, and he goes on about how much he enjoys hearing it.
Outfits! (hats are no longer cool): Monk's robe, until monks are not cool that is. The fez does make a couple of cameos.
Small Child!: Clara's babysitting two of them, and another one turns up in the cafe. Miss Kizlett turns out to be one on the quiet.
Murray Gold's Top Ten: Abysmal Disney kids' movie comedy music as the Doctor gets changed.
Clara Dies Due To: Being zapped by the spoon-head, then revived as above. Twice.
Clara's Job of the Week: Child-minder.
“Run, you clever boy, and remember”: turns up as a painting title and a wifi password mnemonic.
Topical Reference to Puzzle Future Generations: the London Riots of 2011 were apparently down to the baddies as well. There's something which can be mistaken for a Tardis at Earl's Court (no doubt in the Doctor Who Exhibition, though Matthew Kilburn points out that there's also a police box in Earl's Court Road).
Gratuitous Plot Hole of the Week: Who gives Clara the Doctor's phone number as a helpline, and why?
Continuity Frakup of the Week: Miss Kizlet probably ought to be a younger person; she was picked up by the Great Intelligence as a child and the wifi operation can't have been running for longer than about ten years, and yet she's clearly in her sixties.
Nostalgia UK: Reverse nostalgia-- the Shard is new, but give it ten years and setting a story on the Shard will sound like setting one on the Post Office Tower.
Item Most Likely to Wind Up as a Toy: No really marketable monsters this week, so we'll have to settle for Clara, and the Doctor in yet more outfits, spoonhead format, and so forth. “Summer Falls” is already a downloadable e-book.
