- Cue Irony: One of the actors playing the ant-monsters the Zarbi broke his back thanks to the uncomfortable costumes, and many more of them ended up with permanent back problems as a result.
- Fight Scene Failure: The serial was forced to have some seriously awful fighting scenes in it, as the monster costumes used were so delicate.
- Oh lord. Mostly in regards to the insect Halloween-costumes getups and ridiculous mannerisms of the bee-like Menoptra and grub-like Optra as well as the enemy Zarbi, who look like giant ants with a single pair of human legs and two pairs of useless ant legs and make siren noises at each other. Also, one of the Manoptra constantly calls Ian "Heron" for no apparent reason.
- And those of us who have played Assassin's Creed get an additional helping of narm because the villain is named the Animus.
- In his review of the episode, Nash Bozard remarked that the substance used to destroy the Great Old One was essentially giving it cancer.
- Retroactive Recognition: Hilio is played bu Martin Jarvis, who later became noticeable as the later voice for Nergal from The Grim Adventures of Billy & Mandy.
- "Seinfeld" Is Unfunny: It was well liked in 1965, but is downright laughable today.
- Special Effects Failure:
- The Zarbi would look rubbish even if they didn't have two obviously human legs in trousers and shoes sticking out of the bottom and even if they didn't constantly make incredibly synthetic beeping noises. The Larvae Guns are fringed with rags. The Animus and the Menoptera are better-looking, but the Menoptera's wings, which look striking when stationary, rustle in a plasticy way when they move them, and the Animus is obviously just a bunch of hoses glued to a hula-hoop like structure and hung off the ceiling with wire. The tube-like structures the Animus uses to communicate with the Doctor are supposed to look like webs, but instead are just clear plastic drums with some web stuff glued on them - Lampshaded when the Doctor calls one a 'silly hairdryer thing'. Attempts were made to obscure the lousy special effects by greasing the camera within an inch of its life, and it doesn't work. On the plus side, the Wire Fu flight of the Menoptera is extremely convincing thanks to some clever camera angle trickery and the graceful motions of the actors.
- The Zarbi also suffer from the fact that the costumes were so delicate that the Doctor and Ian couldn't actually touch most parts of the costume when fighting them, which both actors said made the job unbearably hard. This led to a lot of Fight Scene Failure - for instance, in a scene where Ian fights the Zarbi, he does a weird manoeuvre where he drops to his back and kicks it away with both legs, simply to ensure he could drop a controlled blow on it at the one point he knew wouldn't fall off (the Zarbi's torso). On top of that, many of the actors playing the Zarbi developed back problems as a result of the uncomfortable costumes and the way they forced them to move. The BBC even had to have special stools made for them.
- There's also the famous Blooper where one of the Zarbi accidentally bumps into the camera...
- What Do You Mean, It's Not Political?: The general line in fan analysis is that the story is a Red Scare allegory, because it's about the Zarbi workers rising up against their Menoptera masters. But it's a really big reach - there's no absolutely no indication the Zarbi are any more intelligent than farm animals, and even though the monster in the story has the power to control gold it doesn't work in any way analogous to any kind of economic system, which seems like it'd be a no-brainer for an anti-communism story. Maybe it's just a Planetary Romance Xenofiction runaround with pretty butterfly people fighting the ant people?
- Not only that, but if you do approach the story as an anti-Communist parable, it says that the workers were totally content until an evil outside force stirred them up and expects us to root for aristocrats who compare the working class to cattle. Way to make your (hypothetical) own side look bad, Bill Strutton.
