- Designated Hero: Throughout the story the Doctor attempts to persuade the villains that although their goals are noble, they are trying to achieve them by blowing things up, and there should be another way. But then, instead of actually bothering to find or even propose another way, he just blows the villains up.
- Don't Shoot the Message: The gist of the Doctor's speech at the end.
- Fridge Brilliance:
- The last time we saw Mike Yates he'd been Mind Raped by a corrupt industrialist and nursed back to health in a hippie commune. Little wonder he joined Operation Golden Age.
- The Brigadier is strangely quick to forgive Mike for his betrayal. However, since this is the same man who ordered the total genocide of a sentient, hibernating race (in a story written by the same writer no less) it's easy to see why he would sympathise with Yates's actions.
- General Finch is so anxious to clear the looters from London not only to distract UNIT from solving the real problems, but because Operation Golden Age really doesn't want anyone else, especially the kind of people who would become looters, contaminating their new utopia.
- Hilarious in Hindsight:
- Magnificent Bastard: Sir Charles Grover and Professor Whitaker. Their plan was to turn back time to land their chosen few in the Mesozoic, undoing everything that had happened since. They also arranged that the head of the British Army's operations in London would be in on it, too.
- Narm Charm: For some viewers, the special effects are so hilariously bad that they swing all the way around to delightful.
- Special Effects Failure:
- A major example. To say the dinosaurs were crap is a bit of an understatement. Someone from the effects team knew someone else who had an effects team in Pinewood Studios who specialised in making puppets, and assured Barry Letts and Terrance Dicks that they would be able to have convincing dinosaurs. Convincing dinosaurs were in no way delivered, and Dicks gleefully notes in a DVD Easter Egg that the company went out of business after the episode was made, for reasons obvious upon viewing. They are so bad that the producer actually begged The BBC to destroy all the copies out of personal embarrassment (all episodes of this one, ironically, survive).
- Even the producers acknowledged the sub par effects... but they're not talking about the dinosaurs. On the special features for "Robot", the producers mention how some of the effects were further compounded by compositing dinosaurs shot on video with footage of the humans (and Time Lord) on film. (It was brought up on "Robot" to explain why they averted Video Inside, Film Outside for similarly compositing something in outdoor footage.
- A comparatively minor example, but the Tyrannosaurus rex in the episode doesn't actually roar and instead literally says, "Roar!"
- They Wasted a Perfectly Good Plot: The main plot is actually generally regarded as being pretty good, sometimes even the best story of Season 11, and the scenes set in the deserted London are very atmospheric. Unfortunately, the massive failure to convincingly realize the dinosaurs on-screen tends to overshadow the story's merits. It often shows up on lists of serials that would benefit from a George Lucas Altered Version like "Day Of The Daleks".
