The Love Hypothesis Rotten Tomatoes Score Revealed

Lili Reinhart’s new romantic comedy The Love Hypothesis Rotten Tomatoes score has arrived as Amazon prepares to release the highly anticipated adaptation of Ali Hazelwood’s bestselling romance novel. The movie, starring Reinhart opposite Tom Bateman, brings one of BookTok’s most recognizable STEM romances to the screen, with early reviews offering a mix of praise for its charm and criticism of its emotional pacing.

The film arrives on Prime Video on September 23, 2026. According to Forbes’ September 22 report, the movie had reached an 80% Rotten Tomatoes critic score as reviews began arriving. Rotten Tomatoes’ listing has since shown the score moving as additional reviews were added, demonstrating how early scores can change significantly around a release date.

That early reception gives fans an interesting first look at how the adaptation is performing before audiences have had much time to see it. More importantly, the reviews suggest that The Love Hypothesis succeeds in some of the areas romantic-comedy fans expect while struggling with one of the genre’s most important ingredients: emotional tension.

The Love Hypothesis Rotten Tomatoes Score Arrives

The initial The Love Hypothesis Rotten Tomatoes score was reported at 80% by Forbes shortly before the movie’s Prime Video debut. That put the film in the “Fresh” territory on Rotten Tomatoes at that point in the review cycle.

The score is particularly notable because The Love Hypothesis enters an increasingly competitive market for book-to-screen romance adaptations. Recent years have seen major attention around movies based on popular romance novels, especially stories that developed large online communities before receiving film adaptations.

Rotten Tomatoes currently lists the movie as a 2026 romance comedy directed by Claire Scanlon, with Lili Reinhart playing Olive Smith and Tom Bateman portraying Adam Carlsen. The movie is distributed through Prime Video and has a September 23 streaming release date.

Because reviews were still being added around release, the exact percentage should be treated as a changing snapshot rather than a final permanent measurement.

What Is The Love Hypothesis About?

The Love Hypothesis follows Olive Smith, a Ph.D. candidate whose academic ambitions take center stage in her life. Her situation becomes complicated when her best friend, Ahn, develops feelings for Jeremy, a man Olive had previously been interested in.

Trying to convince Ahn that she has moved on, Olive unexpectedly kisses Adam Carlsen, an intimidating professor known for his difficult personality.

The spontaneous moment creates a fake-dating arrangement between Olive and Adam.

What starts as a practical agreement gradually becomes more complicated as the two characters spend more time together. Their relationship follows familiar romantic-comedy territory, including fake dates, awkward public appearances and the gradual possibility that the relationship could become genuine.

Rotten Tomatoes describes Olive as a brilliant Ph.D. candidate whose fake relationship with Adam eventually forces her to reconsider whether love is worth taking a risk for.

That setup gives the movie a familiar romantic-comedy structure while placing the story inside the world of academic research and STEM.

Lili Reinhart Leads the Prime Video Romance

For Reinhart, The Love Hypothesis represents another opportunity to move beyond her best-known role as Betty Cooper on Riverdale.

In the new movie, she plays Olive as an intelligent but socially awkward scientist whose confidence varies depending on the situation. The role requires Reinhart to balance comedy, romance and vulnerability while carrying much of the movie’s emotional perspective.

Early reviews have generally recognized Reinhart as one of the movie’s strongest elements.

The Guardian, reviewing the movie after release, described Reinhart as well suited to the kind of awkward but emotionally engaging character that romantic comedies require. The review also highlighted her ability to bring comedic timing and personality to Olive despite problems with the screenplay and story structure.

That response is significant because Olive is central to whether the movie works. If audiences connect with her, the more formulaic parts of the story have a stronger chance of landing.

Tom Bateman Plays Adam Carlsen

Tom Bateman takes on the role of Adam Carlsen, the intimidating professor who becomes Olive’s fake boyfriend.

Adam is designed around a familiar romance archetype: the serious, intimidating and seemingly emotionally distant man whose relationship with the heroine gradually reveals a softer side.

That dynamic is one of the reasons the original novel became popular. The movie therefore had to translate a character-driven romance into a visual format while maintaining enough chemistry between its two leads.

Early reactions have been mixed on this point.

The Guardian praised aspects of Reinhart’s performance but argued that Bateman’s portrayal sometimes moves too sharply between an emotionally distant character and a more romantic leading-man persona.

At the same time, other coverage surrounding the movie has emphasized the connection between Reinhart and Bateman. Their promotional appearances have helped generate additional interest ahead of the streaming release.

The Movie Has an Unusual Fan-Fiction Origin

One of the most interesting details surrounding The Love Hypothesis is its history before becoming a bestselling novel.

Ali Hazelwood’s original story was reworked from Reylo fan fiction inspired by the relationship between Rey and Kylo Ren from the Star Wars sequel trilogy.

That history makes the casting of Tom Bateman especially unusual.

Bateman is married to Daisy Ridley, who played Rey in the Star Wars movies. That means the actor playing Adam Carlsen in The Love Hypothesis has a direct personal connection to the performer who portrayed one of the characters that inspired the original fan-fiction story.

Forbes highlighted that coincidence while discussing the movie’s unusual path from fan fiction to bestselling romance novel and eventually to a major streaming adaptation.

The connection has naturally become part of the movie’s publicity, especially among fans familiar with the story’s origins.

Critics Praise the Comedy but Question the Romance

The early reviews reveal an interesting pattern.

Several critics appear to enjoy the movie’s lighter moments, particularly the awkward situations created by Olive and Adam’s fake relationship. However, some reviewers argue that the film does not spend enough time developing the emotional tension between the two characters.

That distinction matters in a fake-dating romantic comedy.

The entire appeal of the trope usually comes from watching two characters pretend to be in love before gradually realizing that their feelings may have become real. The emotional uncertainty between those stages is often what creates the biggest romantic payoff.

Mashable’s review praised the movie’s bubbly energy and the performances of its two leads but argued that the film was missing enough “yearning” to make the romantic story fully effective.

The criticism suggests that the movie may work more successfully as a light romantic comedy than as a deeply emotional romance.

The Fake-Dating Formula Remains Central

The fake-dating concept is one of the biggest attractions of The Love Hypothesis.

Olive and Adam begin their relationship with a practical arrangement rather than genuine romantic feelings. That gives the story plenty of opportunities for awkward comedy.

Their early interactions include public displays of affection that neither character initially takes seriously. The contrast between Olive’s attempts to appear convincing and Adam’s more reserved personality creates some of the movie’s comedic moments.

According to Mashable’s review, some of these early fake-date sequences provide the movie with its most entertaining material.

However, the same review argues that the relationship loses some momentum once the story needs to transition from fake attraction into genuine emotional intimacy.

That may be the biggest challenge facing the adaptation.

How Does the Movie Compare With the Book?

Fans of Hazelwood’s novel are likely to approach the film with expectations that extend beyond the basic storyline.

The original The Love Hypothesis became especially popular among romance readers and BookTok communities, meaning many viewers already know Olive and Adam before watching the movie.

The novel’s popularity provides the film with an established audience, but it also creates additional pressure. Readers may have their own interpretation of the characters, their relationship and the emotional progression of the story.

The film cannot reproduce every internal thought from the novel. Instead, it has to communicate Olive’s feelings through performance, dialogue and visual storytelling.

That transition appears to be one of the movie’s more complicated aspects.

The Guardian noted that the film’s rapid pacing and relatively thin fake-dating setup can make the romance feel less developed than expected.

Another review, however, offered a significantly more positive response, arguing that the adaptation improved on aspects of Hazelwood’s original novel.

The difference between those responses shows that viewers may have very different reactions depending on what they value most in the story.

What the Rotten Tomatoes Score Means for Prime Video

The early The Love Hypothesis Rotten Tomatoes score gives Prime Video a useful marketing point as the film launches.

A Fresh score can help attract viewers who are undecided about what to watch, particularly when a movie is based on a popular book.

However, Rotten Tomatoes scores are not static during a film’s opening period. As additional critics submit reviews, the percentage can rise or fall.

The Rotten Tomatoes listing for The Love Hypothesis has already shown changing figures as the review count develops.

That means the initial 80% figure reported by Forbes should be understood specifically as the score available when Forbes published its September 22 article, rather than necessarily the movie’s final critical score.

When Can You Watch The Love Hypothesis?

The Love Hypothesis is not receiving a traditional theatrical release as its primary launch. Instead, the movie is arriving on Prime Video on September 23, 2026.

Rotten Tomatoes lists Claire Scanlon as director, Sarah Rothschild as screenwriter and Amazon MGM Studios as the production company, with Prime Video serving as distributor.

The movie is rated R and falls under the romance and comedy genres.

What Fans Should Expect

Based on the early critical response, viewers should expect a conventional romantic comedy built around fake dating, awkward encounters and an eventual shift toward genuine romance.

Lili Reinhart appears to be one of the movie’s major strengths, particularly when the story gives her opportunities to lean into Olive’s awkward humor and emotional vulnerability.

The bigger question is whether the relationship between Olive and Adam provides enough emotional buildup to satisfy viewers who loved the novel.

For audiences primarily looking for a light, funny romance, the movie’s comedic chemistry and familiar tropes may be enough. For viewers expecting a more emotionally intense adaptation, the criticism surrounding the movie’s limited romantic tension could be more significant.

Either way, the film’s release gives one of BookTok’s most recognizable romance stories a chance to reach a much broader streaming audience.

The Love Hypothesis Begins Its Streaming Era

The early The Love Hypothesis Rotten Tomatoes score offers an encouraging starting point for the Prime Video adaptation, while the critical response shows that the movie has both recognizable strengths and noticeable limitations.

The film benefits from a popular source novel, a recognizable lead in Lili Reinhart and a familiar fake-dating premise. It also has an unusually interesting history, beginning with Reylo fan fiction before evolving into a bestselling romance and eventually becoming a major streaming movie.

At the same time, early reviews indicate that translating the emotional interior of the novel to the screen was not always straightforward.

With The Love Hypothesis now arriving on Prime Video, the next stage belongs to viewers. Audience reactions will provide another important measure of whether Olive and Adam’s cinematic romance connects with fans of Hazelwood’s original story and newcomers discovering the characters for the first time.
