WARNING! THERE MAY BE UNMARKED SPOILERS AND HITLER!
- Acceptable Targets: Nazi Germany and the Third Reich, obviously.
- Broken Base: Downplayed, but while the episode gained a generally favorable reception on release and is still viewed in a mostly mixed-to-positive light, some have complained that the choice to base the episode in Nazi Germany and have it be mostly comical might've been in bad taste.
- Crosses the Line Twice: Anything the Antibodies say.
- Fan-Disliked Explanation: The retconning of the TARDIS's state of temporal grace (which was a plot point all the way back in "The Hand of Fear", and mentioned in passing in "Arc of Infinity") as just being a "clever lie" really annoyed some fans, who didn't appreciate the implication that the Fourth Doctor was just talking out of his ass when he first mentioned it. While no fans actually liked this retcon, many agreed that it was just time to stop pretending the TARDIS had the feature (or at least that it worked reliably), considering how many acts of violence we've seen committed in the console room over the years.
- Foe Yay: The Doctor and Melody Pond/River Song have this to the point where this episode is essentially the proper start of their romance.
- Fridge Brilliance: Hologram-Amelia stating that regeneration has been disabled might be referring to regeneration as a minor healing function, in the same way The Doctor will later heal River's wrist in "The Angels Take Manhattan."
- Fridge Logic: Between "A Good Man Goes to War" and "Let's Kill Hitler," the entirety of Torchwood: Miracle Day happened. You'd think Amy and Rory would mention that nobody on Earth could die for three months, and ask why The Doctor didn't come to help with that, but apparently not. Though in fairness, they were in a bit of a hurry.
- Funny Moments: Surprisingly enough given its setting, this episode is easily one of the funniest in the entire revival's run.
Hitler: Thank you, whoever you are. I think you have just saved my life.The Doctor: ...Believe me... It was an accident...
- The Doctor's realization that he just saved Hitler's life. Then there's Amy and Rory berating him for it.
River/Melody: Ladies and Gentlemen - I don't have a thing to wear! Take off your clothes.
- As mentioned below, Rory punching out Hitler.
- River Song holding everyone hostage in the ballroom and forcing them to strip off their clothes. After Amy and Rory catch up, they see a crowd of screaming people running out in their underwear. Cut to River trying out a few clothes.
Rory: That's not helping.
- After the realization that their best friend from their childhood was actually their daughter, who's also River, and that she's just regenerated and flirted with the Doctor, Rory and Amy's expressions are priceless. Taking in the fact they're in Nazi Germany, Rory says he's getting a banging sound in his head. Amy's response?
Hologram: Your system has been contaminated by the poison of the Judas Tree. You will be dead in thirty-two minutes.
- A blink and you miss it part of that sequence, when River/Melody props her leg up on the chair, the Doctor immediately puts his hand over his eyes.
- River trolling the Nazis by saying she was going to a gay gypsy bar mitzvah for the disabled before deciding that the Third Reich was rubbish so she should go kill Hitler.
- The TARDIS' hologram of Amelia blatantly reminding the Doctor that he's about to die every sentence.
Doctor: Okay, so. Basically better regenerate, that's what you're saying.
Hologram: Regeneration disabled. You will be dead in thirty-two minutes.
Doctor: Unless I'm cured, yeah?
Hologram: There is no cure. You will be dead in thirty-two minutes.
Doctor: Why do you keep saying that?
Hologram: Because you will be dead in thirty-two minutes.
Doctor: You see, there you go again. Basically skipping thirty-one whole minutes when I'm absolutely fine! Scottish, that's all I'm saying.
Hologram: You will be fine for thirty-one minutes. You will be dead in thirty-two minutes.
Doctor: Scotland's never conquered anyone, you know. Not even a Shetland. River needs me. She's only just beginning. I can't die now!
Hologram: You will not die now. You will die in thirty-two minutes.
- Genius Bonus: The first Nazi we meet is called "Zimmerman," which is a bit of a headscratcher since that's typically a Jewish name and that would be a rather big problem in Nazi Germany. However, the name Zimmermann is a common variant that does not have that ethnic connotation.
- Heartwarming Moments:
- When the Interface uses Rose's image. You can tell by the Doctor's face that he remembers how much he loved her, before his expression changes when he remembers his guilt.
- When River/Melody is about to be shot by the Nazis, Rory's "No!" counts as this.
- When Rory and Amy are about to be eradicated by the Antibodies, they say goodbye to each other while professing their love.
- River's Heroic Sacrifice that saves the Doctor from the Judas Tree poison.
- Hilarious in Hindsight:
- Watch this episode, and then look at Peter Capaldi's tenure as the Doctor, where he upgrades to Sonic Sunglasses. It almost makes you wonder what will Jodie Whittaker use instead of a Sonic Screwdriver? A Sonic iPhone?!?
- Mels driving straight through the word "Doctor" in the cornfield causes quite a resemblance to Thirteen's logo.
- Moment of Awesome:
- Rory punching Hitler.
- Amy siccing the Teselecta's own robotic Antibodies on them to save River/Melody.
- Credit where credit is due, the Teselecta manifesting a motorcycle to chase after Melody/River on.
- Pretty much anything Melody Pond does in this episode, though special mention must be given to her weaponizing her regeneration energy against a group of Nazis.
- Nightmare Fuel: The Teselecta itself is pretty damn creepy, being a shapeshifting time-travelling self-appointed "punishers of crimes against humanity" ship staffed by callous Knight Templars.
- Tear Jerker: The prequel mini-episode. Amy's calling on the Doctor's answering machine, asking for the Doctor to tell her what he's learned about her daughter, how he's going to save her, as the camera pans over a seemingly empty TARDIS... until, at last, we see the Doctor's sitting there quietly, listening to Amy's live call, not picking up because he has no answer for her.
Amy: I love you.
- The whole TARDIS interface scene. The Doctor doesn't want to use Rose, Martha, or Donna as the holographic interface due to the extreme guilt he feels about the effect he's had on them, and his dialogue with the Amelia-hologram is equally tragic.
- When River/Melody is going to shot by Nazis, Rory's "No!" is heart-breaking.
- Also when Rory and Amy are about to be eradicated by the Antibodies and they say goodbye to each other.
Rory: I love you too.
- The Doctor begging River to save Amy and Rory while he's helpless from the poison.
- They Wasted a Perfectly Good Plot: A story about the Doctor encountering Hitler himself? Rule of Funny applies, of course, but there are certainly more ways that could have played out than the Führer getting promptly stuffed in the cupboard as a gag.
- They Wasted a Perfectly Good Character: A variant with the Doctor's sonic cane, which despite actually being a pretty creative and interesting tool for the Doctor to use, still has yet to be seen or used after this episode.
- Rewatch Bonus: While it's initially thought to be a side effect of the Judas Tree's poison, this is actually the first episode that states the "Eleventh" Doctor is really the final iteration of their first regeneration cycle.
- Uncanny Valley: Teselecta!Amy is full of this. Probably the creepiest shot in the episode is of Amy desperately screaming for the Doctor's aid to save her and Rory from the Antibodies...but all the audience can see is Karen Gillan standing in the Berlin ballroom with an utterly emotionless expression whilst shouting at the top of her lungs.
- Visual Effects of Awesome: Even ignoring all of the gorgeous regeneration effects in this episode, the Teselecta's shapeshifting effects are pretty damn impressive.
- What an Idiot!: The Teselecta's security system automatically murders anyone without a special device - not only is this pretty barbaric to automatically kill even unarmed and defenseless people, it also means that if the device fails, a crewmember will die for basically no reason. We even see one of the devices fail because the staff's permissions were outdated.
- What Do You Mean, It's Not Symbolic?: In-universe example:Rory: Okay, I'm trapped inside a giant robot replica of my wife. I'm really trying not to see this as a metaphor.
