- Critical Research Failure: Yvonne quotes energy readings in gigawatts at one point. The watt is a measure of power, not energy.
- Hilarious in Hindsight: The Torchwood Institute tries to open a portal to an alternate dimension described as Hell in hopes of turning it into an unlimited energy source, only to unleash an army of horrors upon the world (who took the time to subvert some of their personnel). DOOM (2016) would have the exact same premise involving literal demons.
- What an Idiot!: We learn of the existence of Torchwood, an organization created specifically to fight the Doctor, and alien menaces to Britain in general.
You'd Expect: For them to arm up with special ammunition, like UNIT did back in "Battlefield".
Instead: They use ordinary bullets, and there is absolutely no mention of them having any kind of special weaponry, nor do they even seem to recognize the Daleks and Cybermen at all.
As a Result: They are massacred en masse by the Daleks and Cybermen in the following episode.
For Added Stupidity: They also try Bullying a Dragon by trying to control the Doctor-which, if they've studied their history, they should know never, ever works. It's probably overall a good thing that they were destroyed before they could really try messing with him.
YMMV / Doctor Who S28 E12 "Army of Ghosts"
