I admit to some surprise that there is a George Orwell aficionado in this thread and I'm the only guy connecting some diverse notions, like "The Bells of St. Johns" reminds me terribly of
"Oranges and lemons, say the bells of Saint Clemmons" the nursery rhyme dimly recollected by Winston Smith, and this episode of DW references the plethora of cameras in London, and the Great Intelligence even has a rather 'Big Brother-esque" cameo.
Joined to say that. All the reviews talk about how the episode title was promptly forgotten after ten minutes, but I snapped immediately to Orwell's Nineteen Eighty-four and was watching sharply for related social commentary. And was not disappointed.
But who knows?
