- Misaimed Fandom: Guess what quote is used to justify antisocial behaviour. Sartre had to clarify that he didn't mean hell was all other people in general - he meant that screwed up relationships, poor communication, petty squabbling and minor grudges between people was hell (on top of all the victims in hell being Asshole Victims).
- Moral Event Horizon: None of the characters are there by mistake. Let's see: Ines murdered her cousin because she was in love with his wife, Garcin abused and tormented his wife, and Estelle threw her own baby to her death and then drove her lover to commit suicide.
- Older Than They Think: No Exit is often thought of as the Trope Maker for a Hell where the punishment is being with the rest of the tortured you're with. That concept can be traced back to The Divine Comedy if in a much more unrefined form, where Hell increasingly goes from largely asocial to dangerously anti-social, with thieves stealing each other's bodies, liars beating each other verbally and physically for eternity, and mouths being transfigured from methods of communication to methods of cannibalism in the Ninth Circle.
- One-Scene Wonder: The only other character in the play is the Valet, a Servile Snarker and presumably a demon, who is basically Screwtape meets Figaro.
YMMV / No Exit
