A fake relationship story succeeds when the audience can see the exact moment the performance stops being a performance. The characters can deny their feelings, the plot can create obstacles, and the genre can follow every familiar step, but the transition has to feel earned. The Love Hypothesis understands that formula very well. Its problem is that some parts of the construction are stronger than others.
Olive Smith (Lili Reinhart) and Adam Carlsen (Tom Bateman) enter their arrangement for practical reasons. Olive wants to help her best friend Anh pursue Jeremy without feeling guilty, so she creates a fake boyfriend situation that spirals into an accidental kiss with Adam, the intimidating professor known around campus as Dr. Evil. Adam has his own reason to participate: his position at Stanford is uncertain, and appearing settled with a partner could help convince the university he plans to stay. The setup gives the story a clean foundation. Both characters need something from the arrangement, and the fake romance has a clear purpose beyond simply placing two attractive people in the same room.
The early sections of the film understand this machinery well. The public dates, awkward displays of affection, and increasingly complicated lies create exactly the kind of escalating problems a romantic comedy needs. Director Claire Scanlon gives these scenes room to develop, allowing the humor to come from the characters trying to maintain a story that is becoming harder to control. Olive and Adam are funniest when the film focuses on the gap between their public performance and their private confusion.
The difficulty arrives when the film has to move from the mechanics of fake dating into the mechanics of actual love. Reinhart gives Olive a strong sense of personality from the beginning. She balances Olive’s nervous energy with a deeper insecurity tied to her desire to prove herself as a scientist and maintain the relationships she values. The character feels complete before the romance begins.
Adam is a harder problem. Bateman captures the character’s controlled personality and the gradual softening around Olive, but the screenplay has limited space to explain that transformation. Adam begins as someone who appears distant and almost impossible to read. That creates a clear romantic challenge, but the steps between his cold exterior and his emotional openness are sometimes too small. The story tells us the walls are coming down, yet some of the construction work happens offscreen.
That issue becomes clearer when comparing the central romance with Olive’s friendship with Anh. The film spends time showing why Olive and Anh trust each other and why their friendship drives the entire fake dating arrangement. Rachel Marsh brings energy and warmth to Anh, giving the character a natural connection with Reinhart. Their scenes often carry the emotional confidence that the main romance is still trying to find.
This creates an unusual situation for a romantic comedy. The relationship that begins the plot sometimes feels more developed than the relationship that is supposed to finish it. The screenplay makes a smart decision by preserving the importance of Olive’s friendships, but it also exposes the missing pieces in Olive and Adam’s journey.
The adaptation’s origins add another layer to the storytelling challenge. The Love Hypothesis began as Reylo fan fiction before becoming Ali Hazelwood’s novel, and the film does not completely hide that history. Adam’s black clothing, certain musical choices, and the casting of Tom Bateman, who is married to Daisy Ridley, make the connection difficult for Star Wars fans to ignore. For viewers familiar with that background, the movie becomes a strange exercise in transformation: how far can a story move away from its original inspiration while keeping the elements that made it recognizable?
The answer is surprisingly far, but the references occasionally compete with the story itself. The Star Wars connections are entertaining details, yet the film works best when it focuses on Olive, Adam, and the specific reasons they need each other. A reference can add flavor, but it cannot replace character development.
The supporting cast helps the film maintain momentum when the main romance slows down. Jaboukie Young-White’s Malcolm brings sharp comedic timing, while Anh provides the emotional foundation that keeps Olive grounded. These characters prevent the story from becoming entirely dependent on the central couple reaching a predictable destination.
That destination is familiar, and The Love Hypothesis never pretends otherwise. The film knows the rules of the romantic comedy and follows them carefully. The question is how much weight those rules can carry. The strongest parts of the movie come from specific character choices: Olive protecting her friend, Adam revealing vulnerability, and two people discovering that their arrangement has changed. The weaker moments appear when the screenplay moves between those points too quickly.
The Love Hypothesis is a well-built romantic comedy with a few loose connections in its emotional framework. Its structure is confident, its performances bring charm to familiar material, and its supporting relationships add unexpected strength. The romance reaches the expected destination, but the road there could have used a few more signs along the way.
The Love Hypothesis premieres globally on Amazon Prime Video on September 23, 2026. Adapted from Ali Hazelwood’s bestselling novel, the romantic comedy follows a brilliant PhD student who enters a fake relationship with an intimidating professor to put her scientific theories about love to the test.

The Review
The Love Hypothesis
The Love Hypothesis builds a familiar fake-dating structure with confidence, and its strongest scenes come from the clear reasons Olive and Adam enter the arrangement. Lili Reinhart and the supporting cast bring warmth, though Adam’s emotional shift lacks some of the development needed to make the romance fully convincing. A charming adaptation with a few loose structural pieces.
PROS
- Lili Reinhart’s lively performance as Olive
- Strong friendship between Olive and Anh
- Effective fake-dating setup
- Fun ensemble chemistry
CONS
- Adam’s character arc feels underdeveloped
- Romance progression moves too quickly
- Star Wars connections sometimes distract from the story
