Did You Know?


Doctor mentions Sweeney Todd, who is a fictional character that was popular in Victorian-era melodrama and was also known as "The Demon Barber of Fleet Street." He would dispatch unwary patrons in his barber shop by pulling a lever and having the barber chair they were in drop into a pit. They would then be cut up with his straight razor and served in pies sold in by his co-conspirator, Mrs Lovett. See more »


Just after the T-Rex bursts into flames and the Doctor is heading towards the Thames, he falls from the roof and hangs from the branches. In the shot when the Doctor leaves, moments before Madame Vastra's carriage appears, no tree or tree branches are visible. See more »

Great Fun
23 August 2014 | by pj-busSee all my reviews

Well that was an excellent and fun episode of Doctor Who. I tend to like the ones that are set in historic English settings and I find that trio of characters in London, the reptilian woman, the human woman and the potato like fellow, to be very entertaining.

I've been doing a bit of browsing the web for other perspectives on this Doctor Who and I see that some people like to criticise the script writing of Stephen Moffat. I have not seen every Doctor Who episode by a long way, however I have seen others written by Stephen Moffat and his script writing is excellent as it was in this Deep Breath episode. Stephen Moffat seems to be particularly good at story design. He also sets up rather fine situations. I don't wish to be specific because I prefer not to include any spoilers, however the conclusion to the main drama in this episode really was beautifully done, leaving a great ambiguity about the new Doctor Who, Peter Capaldi.

Peter Capaldi looked to me like a first class Doctor Who. I did like Matt Smith and Tenant but to me Peter Capaldi is the real deal. The first Doctor Who I remember is Pertwee and as a child I loved Tom Baker. However I lost interest in the series after Tom Baker left as I became an older teenager. It was a joy to watch Peter Capaldi in his new role. He is a bit mysterious and dark which I really like. He is so capable, he is able to do the comedy but maintain this slight darkness.

There was one thing which I didn't like about the episode which was the mechanism used to reconcile Clara with the new Doctor near the end. I haven't described it because I don't want to include spoilers. I think Clara should have decided to go with this new strange Doctor all on her own, I think there should have been a scene where she weighed it up, and on balance decided she would join him in his journeying through space and time.

All in all a great episode. Moffat is a great writer and Capaldi is looking like he will be a great Doctor.
