Story summary

Prime Video has released an adaptation of Ali Hazelwood's 2021 romance novel "The Love Hypothesis." The film features Lili Reinhart, who plays Olive Smith, a PhD candidate at Stanford University, and Tom Bateman as Dr. Adam Carlsen, a professor. Olive and Adam engage in an experiment to fake date each other for personal reasons; Reinhart's character is looking for genuine connections while Bateman's character aims to debunk the notion that romance has scientific validity. DECIDER contributor Maddy Casale recommends viewers watch it, describing it as "charmingly cheesy" with classic romantic tropes but not a groundbreaking story. The show premiered on Prime Video and incorporates elements of fake dating and found family dynamics typical in romantic comedies.
