- Base-Breaking Character: Several fans don't like Rickston because he's a smug jackass and one of two survivors who lasts to the end, along with being a Karma Houdini. Among others, though, he's the only tolerable character in the group, who at least snarks at the intolerable ones. It doesn't hurt that upon close examination, he doesn't make the situation worse for anyone.
- Complete Monster: Max Capricorn is a businessman who founded a space cruiseliner company. When his own board of directors votes him out of the company, he attempts to frame them for genocide. Bribing the terminally ill captain of one of the cruise liners to lower shields and allow the ship to be critically damaged by a meteor storm, he causes the deaths of most of the two thousand crew and passengers, with Capricorn reprogramming the ship's robot servants to wipe out any survivors. Capricorn's plan is to have the ship crash into Earth, where the explosion of its engines will wipe out the entire population. The board will be blamed and Capricorn can retire quietly with money he has hidden away. To top it all off he ensures he himself is hidden aboard the ship, so he can watch as his plan comes into fruition. Possessing perhaps the pettiest reasons to commit mass murder in entire franchise, the Doctor rightfully views Capricorn with the disgust and contempt he deserves.
- Darkness-Induced Audience Apathy: One of the main reasons this episode is often detracted. The asshole escapes unharmed, only two decent people survive, and the Doctor is alone and miserable. MERRY CHRISTMAS!
- Harsher in Hindsight: Near the end of the episode, Mr. Copper notes that if the Doctor could have chosen any one person to survive it would not have been Rickston Slade, but he also points out to the Doctor that if he could choose who lives and who dies, "that would make you a monster." Fast forward to The Waters of Mars and this observation proves heartbreakingly accurate when the Doctor's defying a Fixed Point in Time very quickly leads to him getting Drunk On Power; Mr. Copper was right to be wary of an all-powerful Doctor.
- Astrid's fate, being "killed" before being transformed into a likely immortal being roaming the stars, has been called unintended foreshadowing of the fates of later companions Clara Oswald and Bill Potts, both of whom die, are revived in a new form, and then go on to roam the universe; both also express a desire to see the stars much like Astrid does.
- Hilarious in Hindsight: At one point, Midshipman Frame ends up trapped on the bridge, the only thing between him and killer robots being a door, not to mention the faulty power system the ship is running on. Sound familiar?
- Just Here for Godzilla: Partly the reason why it became the highest-rated Doctor Who episode since the show's revival is mainly due to Kylie Minogue fans watching it just for her appearance in the episode.
- What Do You Mean, It's Not Symbolic?: The Doctor gets carried upwards by the Heavenly Hosts, which are designed to look like biblical angels. This scene has been openly criticized by some religious authorities, but there are also people encouraging teachers to use it as an example of resurrection imagery in Religious Studies classes.
