The Love Hypothesis hits Prime Video as critics split on rom-com

The Love Hypothesis arrived on Prime Video on September 23, 2026, bringing Ali Hazelwood's bestselling romance novel to the screen with Lili Reinhart and Tom Bateman in the lead roles. Directed by Claire Scanlon, the adaptation follows Stanford PhD student Olive Smith and Dr. Adam Carlsen as they enter a fake relationship while both have plenty to prove on campus.

The film reaches streaming with sharply divided early reviews. Several critics have praised the chemistry between Reinhart and Bateman and the movie's handling of familiar romantic-comedy conventions, while The Guardian argued that the hit BookTok romance lacks spark on screen.

• Streaming date: September 23, 2026.
• Where to watch: Prime Video.
• Stars: Lili Reinhart as Olive Smith and Tom Bateman as Dr. Adam Carlsen.
• Source: Ali Hazelwood's bestselling novel.
• Director: Claire Scanlon.
• Early reception: Reviews are split, with the final act commonly identified as rushed.

The Love Hypothesis brings Ali Hazelwood's novel to Prime Video

The adaptation keeps the central fake-dating premise at the heart of Hazelwood's novel. Reinhart plays Olive, a Stanford PhD student, while Bateman plays Adam, and their characters agree to a fake relationship as each faces pressure to prove themselves on campus.

That setup places the movie firmly within one of the most recognizable romantic-comedy formulas. The question for reviewers has been less about whether the structure is familiar and more about whether the performances and direction can make that familiarity work.

TheWrap concluded that the fake-dating formula is well-worn but effective here, crediting Scanlon with making established rom-com beats feel fresh. That assessment reflects one side of a critical response that has generally acknowledged the movie's conventional structure even when reviewers disagree about how successfully it translates to the screen.

Prime Video's release also brings one of BookTok's prominent romance adaptations directly to streaming audiences, with the popularity of Hazelwood's bestselling novel forming a significant part of the attention around the movie.

What critics say about The Love Hypothesis

Outlet	Review view
Collider	Praised Reinhart's comic timing and said Bateman's initially rigid performance gradually reveals more of Adam, calling the film a near-perfect rom-com experiment.
TheWrap	Found the fake-dating formula familiar but effective and credited Claire Scanlon with making familiar rom-com beats feel fresh.
Roger Ebert	Said the romantic comedy supports its charming claims.
The Guardian	Called it a hit BookTok romance that lacks spark on screen.

Collider was among the most enthusiastic, highlighting Reinhart's comic timing and arguing that Bateman's performance develops as the movie goes on. Its review described the adaptation as a near-perfect rom-com experiment, emphasizing how the two leads carry the familiar setup.

RogerEbert.com's review also landed on the positive side, arguing that the film supports its charming claims. The Guardian took the opposite view, finding that the popularity of the BookTok romance did not translate into sufficient spark on screen.

The split does not erase areas of agreement. Reviewers repeatedly focus on the two leads, with their “undeniable chemistry” singled out as a strength and the script's classic rom-com patter helping their scenes together.

Lili Reinhart and Tom Bateman lead the fake-dating romance

Reinhart's Olive is positioned at the center of the movie's comic and romantic momentum. Collider specifically praised her comic timing, suggesting that her performance is one of the clearest reasons the formula continues to work even when the story moves through recognizable genre territory.

Bateman's Adam begins from a more rigid place, according to Collider, before the performance gradually reveals more of the character. That progression becomes particularly important in a fake-dating story, where the appeal depends on the relationship changing as the two characters spend more time together.

The Hindu also published an interview with Reinhart and Bateman about the film and the science of romance, extending the conversation around the adaptation beyond straightforward reviews.

Together, the two actors are the part of the film that draws the most consistent praise across the divided response. Even reviews that question the adaptation's overall impact acknowledge the importance of the leads and the traditional romantic-comedy dialogue supporting their chemistry.

Why the final act is dividing The Love Hypothesis reviews

One recurring criticism centers on the final act. Reviews commonly describe that section as rushed as the movie tries to resolve its conflicts, making the ending one of the more consistent weak points identified across the early critical reaction.

That criticism stands apart from the broader debate over whether the movie feels fresh or overly familiar. A critic can respond positively to the leads or Scanlon's direction while still finding that the closing stretch moves too quickly through the conflicts that need to be settled.

The result is a movie drawing praise and criticism in different areas rather than a simple critical consensus. The leads' chemistry, Reinhart's comic performance and the use of classic rom-com patter have attracted favorable comments, while the pacing of the final act has repeatedly emerged as a concern.

The Guardian's more negative assessment goes further, arguing that the screen version lacks the spark associated with the novel's status as a hit BookTok romance. That contrasts directly with Collider's much warmer judgment of the film as a rom-com experiment.

How the Prime Video adaptation compares across early reviews

1. Performance: Reinhart's comic timing receives specific praise, while Bateman's portrayal is credited with opening up as the story develops.
2. Chemistry: Reviewers highlight the leads' “undeniable chemistry”, supported by classic romantic-comedy patter.
3. Formula: The fake-dating setup is regarded as familiar, though TheWrap argues that Scanlon makes those familiar beats feel fresh.
4. Ending: The final act is repeatedly described as rushed as the film resolves its conflicts.
5. Overall response: Reviews range from highly positive to criticism that the BookTok hit lacks spark on screen.

Those points explain why early reactions are so mixed. Critics are largely looking at the same ingredients — a familiar fake-dating structure, two prominent leads and a bestselling source novel — but reaching different conclusions about whether those ingredients produce an effective screen romance.

What happens next for The Love Hypothesis

With The Love Hypothesis now available on Prime Video, the adaptation moves from pre-release anticipation into its streaming life. Viewers can now judge the chemistry, comedy and pacing that have divided the first wave of reviews.

The critical conversation is likely to remain centered on the same contrasts already visible in the early response: familiar rom-com mechanics against strong lead chemistry, and an effective central pairing against a final act many reviewers consider rushed.

For fans of Hazelwood's novel, the September 23 release also ends the wait to see Olive and Adam's fake relationship translated to screen, while the wider audience can now assess whether Scanlon's version makes the established romantic-comedy formula feel fresh.
