- Alternative Character Interpretation: Is Mademoiselle truly a Complete Monster who will torture children to death to accomplish her goals, or simply a philosopher desperate to find out about the Afterlife because of her old age? She justifies her action as For Philosophy but does that merit permission to use torture as the means to discover the secrets of martyrdom? And why did she commit suicide once she found out from Anna what really was the Other World?
- Darkness-Induced Audience Apathy: One of the most nihilistically depressing movies ever made. It starts with the supposed heroine gruesomely gunning down a terrifed family with two kids, Pretty Little Headshots and Gory Discretion Shot both thoroughly averted, and it goes downhill and far far beyond after that.
- Paranoia Fuel: Just think, your completely normal neighbors could have their very own Torture Cellar.
- The Woobie: Arguably the girl rescued by Anna but reduced to feral insanity because of Mademoiselle's tortures.
