It is often observed that works of an episodic nature tend to fall into predictable patterns over time. Plot structures, character personalities and so forth tend to develop comfortable, consistent shapes, often called “formulas”. Many works, of course, use formula and repetition to a specific end—e.g. in service of a specific thematic goal. Yuasa leverages formula in The Tatami Galaxy to viscerally drive home the work’s thesis; untold volumes have been filled dissecting its use in Revolutionary Girl Utena. But what I mean to discuss here is the function that repetition serves more generally as a narrative, not thematic, device—we arrive at formulas because if something worked once, it’s likely to work again. Repetition, used carefully, can enhance a work as much as effective photography or musical score.
