The Love Hypothesis, the screen adaptation of Ali Hazelwood’s BookTok-favourite novel, arrives as a buoyant study in rom-com chemistry — warm, fizzy and precisely calibrated to please. Lili Reinhart and Tom Bateman make for a physically convincing pair, and director and writers have clearly leaned into the novel’s academic setting and prankish use of romance tropes. Yet for all its charms, the film ultimately feels short on emotional weight.
Performance and tone
Reinhart plays Olive Smith, a bright, cheerfully caffeinated biology PhD candidate whose work and romantic entanglements sit at the story’s heart. Bateman is her opposite and on-screen foil, the taciturn professor Adam Carlsen, whose gruff reserve is played for both comic friction and slow-burn attraction. Their chemistry, both literal and figurative, is one of the film’s clearest assets: the leads sell the fake‑dating gambit with physical plausibility and comic timing.
The adaptation keeps the novel’s emphasis on life in STEM academia and the romance tropes that made the book a viral hit on social media, above all the fake‑dating conceit. It also replicates the book’s upbeat, trope‑savvy tone — a blend of affectionate parody and sincere romance that will satisfy many viewers who came for the source material.
Where it falters
Observers of the film have noted a recurring shortfall: beneath the sparkle, the picture seldom builds the sustained yearning that elevates a romance beyond pleasant diversion. As one critic put it:
“missing one key ingredient that would truly make its experiment stick the landing: yearning.”
That lack is felt in the film’s middle stretches, when the setup and jokes keep momentum but the emotional stakes do not quite deepen. The adaptation prefers buoyant moments and procedural plot beats over lingering on the inner life that might turn many of its beats into something more affecting.
Strengths beyond the leads
Production design and the film’s depiction of academic life help sell the conceit: laboratory spaces, conferences and the small rituals of campus research are used as texture rather than mere backdrop. The screenplay, faithful to the book’s structural tropes, offers a string of gags and set pieces that land more often than not.
- Strong points: lead chemistry, comic timing, relatable academic detail.
- Shortcomings: insufficient emotional depth, a tendency to prioritise sparkle over ache.
- Audience: fans of the novel and viewers who enjoy light, trope‑driven rom‑coms.
What this adaptation means
In the current streaming marketplace, adaptations of internet‑born literature carry commercial and cultural significance: they signal how quickly viral book communities can shape film and TV slates. This production will doubtless gratify the book’s existing audience while introducing the story to a wider international streaming viewership. For readers unacquainted with the novel, the film functions well as a self-contained rom‑com — bright, pleasurable and never mean‑spirited — even if it does not quite deepen the attachment to its protagonists.

The Love Hypothesis will find an eager audience and plenty to enjoy: it brims with small, well‑executed pleasures and benefits immeasurably from its central casting. If you’re seeking yearning with your rom‑com, however, you might find the experiment fizzles before the final, resonant reaction. For many viewers, though, that effervescence will be exactly the point.
