Lili Reinhart stars alongside Tom Bateman in Amazon Prime Video rom-com The Love Hypothesis, which has earned generally positive early reviews ahead of release.
The romantic comedy feature film, directed by Claire Scanlon from a screenplay written by Sarah Rothschild, debuts on the streaming platform on September 23, 2026. It adapts the popular 2021 bestselling romance novel of the same name written by author Ali Hazelwood.
Early reactions from film critics describe the movie as a comforting, charming, and predictable addition to the romantic comedy genre. While several reviewers noted that the film relies heavily on familiar narrative clichés, many praised its effective delivery of lighthearted entertainment alongside strong comedic timing from its lead actors.
Critical consensus and lead performances
The central dynamic between Lili Reinhart and Tom Bateman has emerged as one of the primary highlights among initial reviews. Critics frequently pointed to the visible on-screen chemistry and shared sense of humor between the two lead performers as a major factor in driving the story forward.
Writing for Collider, Carly Lane admitted she initially held doubts about whether Reinhart was the right choice to play the main character. However, Lane noted that those reservations vanished as soon as Reinhart shared the screen with her co-star. She described the lead character as sweet, highly intelligent, and slightly idealistic, adding that Reinhart's performance was endearing due to her comedic timing and her judgment in letting her co-star shine.
Reinhart is widely known for her breakout role as Betty Cooper in the long-running teen drama series Riverdale, as well as her film appearances in Hustlers and Look Both Ways. Bateman, an English actor, previously starred in major film adaptations including Murder on the Orient Express and Death on the Nile.
Ekta Sinha of Elle praised the chemistry between the two leads, stating that their dynamic turned standard fake-dating tropes into an exciting experience. Sinha observed that the film effectively captured the tension and awkwardness of transitioning from a fake relationship to genuine feelings, noting that the romantic storyline maintained strong pacing and understood the value of narrative anticipation.
Supporting cast and adaptation details
Alongside the main leads, supporting cast member Rachel Marsh received explicit praise for her portrayal of Anh, the fiercely loyal best friend of the protagonist. Reviewers highlighted Marsh's dynamic presence as an anchor for the surrounding ensemble cast.
The supporting lineup also features Nicholas Duvernay, known for his work on HBO series The White Lotus, Jaboukie Young-White from Companion, and Arty Froushan from Daredevil: Born Again. In her review for IGN, critic Tara Bennett praised the supporting cast, specifically noting that Marsh and Young-White provided excellent comic backing to the central romance in a fun and passionate book-to-screen adaptation.
The narrative follows Olive, a biology doctoral student at Stanford University in California. In an effort to convince her friends that she is in a happy relationship, Olive enters into a fake dating arrangement with Dr. Adam Carlsen, a brilliant young professor known across campus for his strict and intimidating personality. Despite their formal agreement, real feelings soon begin to develop between them.
Director Claire Scanlon previously directed the acclaimed 2018 romantic comedy Set It Up, while screenwriter Sarah Rothschild developed the film script directly from Hazelwood's original book. The story takes place within the competitive environment of academic science, technology, engineering, and mathematics.
Mixed reviews on plot tropes and tension
Despite the generally favorable reception, several critics expressed reservations regarding the film's reliance on standard romantic comedy conventions. Some reviewers argued that the screenplay followed predictable genre steps without offering significant narrative innovation.
Writing for Mashable, Belen Edwards noted that while the overall feature did not completely cohere, it still found genuine charm through the comedic chemistry displayed during the initial fake dates between Olive and Adam.
In a review published by The Wrap, William Bibbiani pointed out that the script moved systematically through classic romantic scenarios. He described the plot as following two seemingly incompatible individuals who initially could not picture themselves together before gradually discovering that they did not want to be apart.
TechRadar critic Jasmine Valentine took a more critical stance, writing that the movie played it safe across its direction, narrative, and soundtrack, which she described as disappointing. However, Valentine acknowledged that the overall journey remained entertaining and sincere, adding that the story resonated by reflecting the real difficulties faced by women working in academic STEM fields.
Divergent opinions on romantic chemistry
Other reviewers identified areas where the adaptation fell short of its literary source material. Certain critics noted a lack of prolonged romantic tension, suggesting that the narrative missed an essential spark of contained desire between the main characters.
Molly Freeman of Movieweb called the film a solid adaptation of Hazelwood's novel that successfully translated key story elements and character traits to the screen. However, Freeman observed that the limited runtime prevented the movie from developing the characters to the same depth found in the book. She added that a perceived lack of on-screen chemistry between the leads ultimately prevented the film from being a mandatory watch.
Amazon Prime Video will release The Love Hypothesis globally on September 23, 2026, making the long-awaited adaptation available to subscribers worldwide.
