Capaldi is just blowing me away. He's in Tom Baker territory now in terms of my favorites and that's with writing that sometimes leaves me cold.

I found it a little hard to follow the action, but I’m waiting for the next one to see how they fit together.

For purposes of this discussion, the original Osgood will be O, the first Zygon to duplicate her will be O'.

No, that's just incorrect. Nothing in the Doctor's plan prevents humans and zygons from achieving an actual peace.

To be totally honest, I kinda can. I mean, when Harry met the Zygons, it wasn't just Invasion of the Body Snatchers, it was also a side order of Godzilla, where London is in danger of being leveled by the Skarasen (sp?). I can see Harry doing it and being proud of protecting Earth from invading aliens without any…

There's also an 11th Doctor audio book where Smith voices a passel of cowboys. I'd say it was a lateral move from Last Voyage.

That reminds of Troughton trying a Mexican accent in Enemy of the World. It was…one way to go…

He did an episode of Remington Steele way back in the day. I can't remember whether he did an American accent or not.

I'm still laughing at him bringing "Doctor Disco" back again in this one.

Smith had a whole battery of little "Old Man" tics and quirks that were a lot of fun, but for real heartsick weltschmerz, you just have to have some lines on your face.

Also, I loved that everyone else referred to it as "Sullivan's" gas, and the Doctor called it "The Imbecile's." Lovely Tom Baker call-back.

A+ episode. This is going to be the definitive Capaldi episode.

That makes sense. I was thinking Tenerife,since they filmed bits of Magician's Apprentice there. They probably did it all on the same trip.

Woah! This may have come up in the comments already, but at the UNIT safe house in South London, there's a portrait of Bill Hartnell's Doctor!

"I’m not sure that’s something the show really ought to be
given credit for, exactly, given the twist works in large part because
it takes advantage of a more systemic weakness of this current era."

Stop showing us people's journey to the Dark Side! For fuck's sake, just let us have a cool bad guy!

Someday, I need to figure out what the hell is going on with all the rights to Doctor Who stuff. I've heard it only takes 10,000 hours to master any skill so maybe I can figure this out.

Very possibly true (although I wouldn't bet the rent on your demographics). But the question was put as to why anyone wouldn't like Capaldi. I can only answer honestly why I came close to writing off Capaldi (consideration that I was seeing things through an American lens is one reason I decided to stick it out),…

I knew someone would actually do this, but it's worse than I thought. So, you're calling Leo Jones a "major role?" That's great. Good for you. You win the argument! I'll be over here, not bothering to explain why the Doctor's withering condescension and assumption that Danny was a PE teacher made him look like a…

My meaningless fan-theory used to be that it's easier if you stay on Gallifrey, near the Matrix. That's why it always went sideways for the Doctor and the Master (who eventually had to resort to body-stealing), but Romana, who had only left recently, was good at it.
