Did You Know?


There is a real town in New Mexico called "Truth or Consequences." The town's name was changed from "Hot Springs" on 31 March 1950 after Ralph Edwards, the host of the popular game show "Truth or Consequences," called for any town in America to do so - in celebration of the show's ten year anniversary.

The policewoman in New Mexico has what appears to be an Italian flag patch on her uniform. This is apparently an attempt to approximate the flag of Mexico, which uses the same tricolor as the Italian flag, but with a coat of arms in the center. The costume department apparently believed that Truth or Consequences was in the country of Mexico rather than the American state of New Mexico. See more »


Kate: It's a nerve gas. Unravels their DNA. Basically turns them inside out.
Clara Oswald: Where do you keep it?
Kate: We don't. It was taken. The formula, the lot.
Clara Oswald: Who took it?
Kate: Somebody with a Tardis.

This was when I finally, sadly, gave up on Doctor Who altogether
8 November 2015 | by cheroldSee all my reviews

It's been coming for a while now. The season's opening story was somewhat interesting, but that was owing entirely to Missy (the actress would have been made a good Doctor, really). Outside of that, I was underwhelmed.

And I kept on being underwhelmed. Nothing was awful, but the series felt like it had finally, completely run out of ideas. Individual stories felt like more of the same, and there was little indication of the sort of grand, tricky story arcs that have been Steven Moffat's saving grace.

By The Girl Who Died/The Woman Who Lived, I was seriously considering whether Doctor Who was still worth watching. I was a little shocked at myself. During the Russell Davies years, and even during the early Moffat era, there was no show I was more excited to watch each week than Doctor Who. It was my top show. Could I really just ... stop watching?

As I was watching this episode, which felt so similar to so many episodes before (where are the ingenious new ideas like deadly statues that the series once threw at us with suck reckless abandon?), I realized it was time to stop. I was in the middle of the episode, and I didn't care what happened next. Not at all.

It's not the actors. I always liked Clara, and I like the new Doctor as much as I liked the last one (in both cases, not nearly as much as the first two). It's the writing. The writing has gone to s***. There's no other way to put it. The show is devoid of fresh ideas. This episode is simply a matter of raiding old ideas to piece together a new episode.

Doctor Who is not a terrible show. But it is no longer a wonderful show. There are so many better series out there (The Strain, Haven) that I just don't have time for it anymore.

Will I ever watch the show again? I might look in if I hear Missy is back. Or I might not. It might take a change of show runner to get me back. This series is completely out of steam. It makes me sad.
