- Fandom Rivalry: The Darker and Edgier Ehlinger-Whalen adaptation versus the Lighter and Softer Travis-Caplan adaptation.
- Fridge Brilliance: The main character is named A. Square, because that's the shape that the character has. However, once one realizes that the author's name is Edwin Abbot Abbot, which for the mathematical types can be represented as Abbot Squared, then it becomes a sly self-reference.
- Misaimed Fandom: Satire of Victorian classism and sexism? Most come to it because of its depiction of higher dimensions.
- The Scrappy: The title cards in Flatland: The Film that constantly interrupt the story to deliver exposition, often doing so in an annoyingly condescending manner. Quite a few critical reviews claim that the Narration single handedly ruined the entire film for them.
- Values Dissonance:
- A 3-D sphere tells the hero, a 2-D square, that in his world, men and women are equals. The square finds this unbelievable. The author might have been hinting that in a more advanced world, the sexes would in fact be more equal than in his time.
- The epilogue in later editions of the book would seem to indicate that people found it sexist at the time.
- As well, later editions rewrote it so that the square admits how bad women have it, noting that the only "consolation" is that they can't remember all the injustices they suffer.
- We might be dealing with an Unreliable Narrator as to how poor women's memories are. The square's wife comes across as sort of, well, ditzy, but she seems to remember things longer than he claims women do. (He does say she's smarter than most, but if women generally were as dumb as he claimed, they'd never remember where they lived or that they had families if they left the house. Or all the laws they have to follow).
YMMV / Flatland
