Did anyone else take Jenny's black leather scene to be a nod to Diana Rigg's Emma Peel days?
I recall the outfit first appearing in 'The Snowmen', so it wouldn't have been created specially as a tribute to Mrs. Peel (Unless Dame Diana had already been cast for this back then). But on the other hand, I can easily imagine Moffat in a production meeting pushing the virtues of black leather. He is a cult TV fan, after all, and I'm sure he'd like a Mrs. Peel type in his show.
And after the implied oral sex reference in 'A Good Man Goes To War', here we have the Doctor see a gorgeous young woman strip off her maid's outfit to reveal the leather underneath, and his sonic screwdriver goes vertical. Hmmmm....
And was it just me, or was some of the music (near the start, before it got---once again---too loud and bombastic) deliberately reminiscent of Sherlock?
