Thompson’s novel is premised on a psychological concept: When faced with overwhelming chaos, humans often seek patterns and rules to make sense of the incomprehensible. In How to Kill a Guy in Ten Dates, Jamie applies this instinct literally, using her academic knowledge of slasher films as a survival guide during a real-life massacre. The novel explores the dual nature of these fictional formulas, demonstrating how they can serve as both a crucial framework for navigating danger and an inadequately simplistic lens for a complex reality. While Jamie’s adherence to the rules of slasher films provides a lifesaving strategy for her escape, her ultimate survival depends on her ability to recognize when the killer is subverting those same conventions and to adapt her strategy accordingly.

Initially, Thompson frames Jamie’s expertise in genre theory as a pragmatic and effective tool. The “How to Survive a Slasher” poster in her apartment becomes a mental checklist that dictates her actions (xi). In the initial basement attack, she follows Rule Two, “ALWAYS HIDE FOR LONGER THAN YOU THINK YOU SHOULD” (xi), which keeps her and her best friend Laurie safe. Immediately afterward, she follows Rule Three, “FIND A WEAPON” (xi), by arming them with broken bottles. Later, she vehemently rejects Stu’s suggestion to separate, declaring, “Splitting up just makes it easier to get lost or to become a target” (63), a direct application of Rule Five, “DON’T SPLIT UP” (xi). In these moments, the predictable structure of the slasher film provides a clear and logical path through the terror, allowing Jamie to make decisive choices while others are frozen by panic.

However, as the killer’s violence escalates, Thompson complicates this reliance on formula by revealing that the killer, John, is just as genre-savvy as Jamie. He and his accomplice, Billie, deliberately manipulate slasher and romance tropes to mislead and trap the survivors. They create a trail of rose petals—a romantic cliché—that leads to two dead bodies and a dead-end corridor, leading Jamie and Wes where they want them to go. They strategically hide the building’s only accessible exit, a door to the roof, behind a barricade of furniture, which conceals the club’s exit. Eventually, Jamie recognizes that “[t]hey used the rules against us,” noting:

In the movies, dark and scary means death, not salvation. That’s why the lights were smashed, furniture was scattered, and the walls were marked. John and Billie were trying to make it look like the kind of place where you’d meet your end, not the kind of place where you’d find your escape. (309)

This subversion demonstrates the challenges of assuming a killer will follow a predictable script, highlighting the limitations of applying a rigid fictional framework to an unpredictable human adversary.

In the novel’s climax, Jamie survives by synthesizing her knowledge and creating her own strategy rather than following formulaic rules. Recognizing that John sees the massacre as a twisted rom-com, she adapts her approach. In the final confrontation, she stops adhering to slasher conventions and instead plays the part of the rom-com’s leading lady, luring John to the dance floor with a bouquet of roses. This performance, rooted in her understanding of romantic tropes, allows her to get close enough to strike. She uses the rules of one genre to set a trap within another, becoming the author of her own ending rather than a character following a pre-written script. The novel argues that while fictional formulas can offer a guide, true survival lies in the creative intelligence to interpret, adapt, and ultimately rewrite the rules.
