The Love Hypothesis Tests a Familiar Romantic Formula
The Love Hypothesis turns science into romantic experimentation as a shy graduate student creates a fake relationship with her intimidating professor, only to discover that some forms of chemistry are considerably harder to control.
Olive Smith (Lili Reinhart) dreams of changing the world through science. Brilliant in the laboratory but shy and introverted everywhere else, she is far more comfortable conducting experiments than navigating relationships. Her social life changes when fellow student Anh (Rachel Marsh) gravitates toward her, and the two quickly become best friends. When Jeremy enters the equation and Olive realizes he may also have feelings for Anh, she decides to remove herself from the romantic competition and convince her friend that she has already moved on.
Her solution is impulsive, ridiculous, and perfectly suited for a romantic comedy: kiss the first available man she encounters.
Unfortunately, that man is Dr. Carlsen (Tom Bateman), a professor whose reputation as a ruthless disciplinarian has earned him the campus nickname “Dr. Evil.” Rather than ending Olive’s experiment before it begins, Carlsen agrees to participate. With a grant under consideration and questions surrounding his future at the university, appearing settled gives his colleagues another perspective on a man better known for terrifying students.
The two establish their parameters: they will be seen together around campus and attend university events as a couple, but the relationship will remain strictly performative, with sex firmly outside the experiment. Of course, everyone watching knows exactly where this hypothesis is headed.
When Fake Chemistry Becomes Real
The fun comes from watching two people who are considerably better at understanding scientific variables than emotional ones attempt to convince friends and faculty that their relationship is genuine. Initially, their interactions are painfully awkward, particularly because Carlsen’s reputation makes the idea that anyone would voluntarily date him difficult for the student body to comprehend. But the more time Olive and Carlsen spend together, the less convincing they have to do. Their emotional defenses gradually weaken, and the relationship designed to fool everyone else begins fooling the two people who created it.
Based on Ali Hazelwood’s 2021 novel, The Love Hypothesis arrives as a Prime Video adaptation of the bestselling romance, written by Sarah Rothschild and directed by Claire Scanlon, whose previous relationship comedies include Set It Up and The People We Hate at the Wedding. Scanlon understands the mechanics of this kind of romantic comedy, but the movie rarely finds a way to escape them.
The story is predictable, fluffy, and deliberately light. Five minutes into the film, audiences already know where Olive and Carlsen are going. The remaining questions are how long it will take them to get there and what complications will stand between them and the inevitable conclusion.
Predictability isn’t necessarily fatal to a romantic comedy. Knowing the destination can be part of the comfort. The problem is that the journey doesn’t generate enough distinctive personality to make this familiar route feel particularly fresh. Despite Scanlon’s experience with the genre, there is a strangely vacuous quality to the proceedings. The film understands the formula but rarely discovers enough beneath it to turn a pleasant diversion into something memorable.
The Love Hypothesis Finds More Interesting Questions in the Lab
Where the movie becomes considerably more interesting is when it looks beyond romantic chemistry and toward the power dynamics surrounding Olive’s scientific ambitions.
Her academic career places her within a familiar historical pattern in which younger women scientists can find their ideas dismissed, appropriated, or credited to more established male colleagues. For Olive, having the right idea isn’t necessarily enough. She must also navigate an institution where reputation and professional standing can determine who receives recognition for the work.
The film takes that imbalance into darker territory when professional authority becomes sexual leverage. Harassment carries an additional threat because challenging someone with greater institutional power can put the younger scientist’s own reputation and career at risk. Funding, recommendations, access, and professional advancement can all depend upon people further up the academic ladder, creating an environment where the person with the least power potentially has the most to lose by speaking out.
Suddenly, Olive’s predicament carries consequences far greater than whether her fake relationship becomes real. Her work, credibility, and future are vulnerable to people who understand exactly how much institutional power they possess.
Those ideas give The Love Hypothesis a more substantial conflict than its romantic setup initially promises. Unfortunately, the movie doesn’t probe them with the same curiosity Olive brings to her scientific work. They become complications within the larger romantic narrative rather than the foundation for a deeper examination of gender and power in academia.
The casting creates another distraction. Although the story takes place in graduate school, several performers feel noticeably older than the characters they’re playing, creating a disconnect that takes some adjustment. The ensemble, which also includes Jaboukie Young-White and Nicholas Duvernay, is serviceable, but the material gives them limited opportunities to elevate the familiar machinery surrounding them.
The Real Love Story May Be the Friendship
Interestingly, the most convincing relationship in The Love Hypothesis isn’t necessarily the romance between Olive and Carlsen.
It’s Olive and Anh.
Olive’s entire scheme begins because she cares about her friend enough to remove herself from what she believes could stand between Anh and happiness. The decision may be misguided, but the impulse reveals something genuine about their relationship. As Olive stumbles through her fake romance, academic pressures, and the increasingly real emotions it creates, Anh remains an important part of her journey.
Their friendship gives the movie a warmer emotional foundation than the predictable romantic complications surrounding them. In that sense, the men almost become supporting players in another kind of love story. Olive and Anh are experiencing this chapter of their lives together, navigating relationships, careers, uncertainty, and adulthood while strengthening a friendship that may ultimately prove more enduring than any romantic experiment.
That idea, combined with the film’s examination of the obstacles confronting young women attempting to establish themselves professionally, gives The Love Hypothesis something more interesting to say than its familiar fake-dating setup initially suggests.
The Love Hypothesis: Final Verdict
The Love Hypothesis understands the formula of the modern romantic comedy but doesn’t discover a particularly revolutionary result. Reinhart and Bateman generate enough chemistry to make Olive and Carlsen’s inevitable journey watchable, while Scanlon keeps the proceedings moving with the light touch the material requires. But familiarity eventually becomes the movie’s greatest limitation. The film checks the necessary boxes without finding enough surprises between them.
Ironically, its most compelling ideas exist outside the central romance. Olive and Anh’s friendship feels genuine, while the movie’s exploration of women navigating scientific institutions where established men can control credit, opportunity, and reputation provides glimpses of a more substantial story. Had the film allowed those ideas to become as important as determining when Olive and Carlsen will finally acknowledge the obvious, its romantic formula might have produced a more interesting result.
Its saving grace may be exactly where audiences will encounter it. A theatrical release could easily have allowed this modest romance to disappear among stronger films, but streaming gives it a more natural laboratory, where viewers looking for something light, comfortable, and undemanding can discover it without requiring the movie to become something larger than it is.
We’re constantly told that love conquers all, but the hypothesis presented here produces something closer to a false positive. I’m positive The Love Hypothesis will provide an agreeable diversion for its target audience, and I’m equally positive that shortly afterward, much of it will become a distant memory.
And that is absolutely not false.
The Love Hypothesis streams on Prime Video beginning September 23.
