YMMV: Alien Nation
- Fridge Horror: More than likely, the Overseers are going to come for their former slaves sooner or later. Who's to say that they won't decide to subject humans to the same fate as the Newcomers?
- This was the plot of the first TV-movie, and was only averted when the advance leader, Ahpossno, realized that he had repaid kindness the Earth-bound Newcomers had shown him with treachery and deceit, and they had in turn ensured he would never live to see the enslavement of Earth.
- In the series, there was an episode where overseers tried to contact a probe that came looking for them. They missed, but it was damn close. The overseer who tried to do this explicitly referred to the human population as cargo, just like to the Tenctonese, so the overseers WILL try to kidnap all the humans as slaves.
- However, in "Dark Horizon," Ahpossno returns to the Overseers' fleet almost dead as a result of the disease George infected him with. He essentially does a Heel-Face Turn and with his last breath tells the Overseers to stay away from Earth because the Newcomers are all dead from the disease. So it seems unlikely they'll show up.
- Hilarious in Hindsight: In "Fifteen with Wanda," George tells Matt that he, George, is not doing well at parenting. He picks up a book and says, "And this 'Mister Spock' book is no help!" "It's Doctor Spock," Matt says. "Mister Spock is one of you guys." Gary Graham went on to play Vulcan Ambassador Soval in Star Trek: Enterprise, so Mr. Spock is actually one of his guys.
- Mary Sue: With the arguable exception of the Overseers (or Kleezantsun'), the entire Tenctonese species (or at least the genetically engineered former slaves).
- Narm: The slur "slag" can be for British viewers as it is also a British slur for a promiscuous woman.
- Nightmare Fuel: The levpa in the Expanded Universe novel.
- Woobie Species: The Newcomers, who exist to teach us An Aesop about racism and a ton of other subjects.
