Book vs. movie: what changed

Book-to-film adaptations always cut, condense, or rearrange. The Regretting You movie follows the major beats of the novel but compresses the timeline and streamlines subplots to fit a two-hour runtime.

Spoilers below

This section discusses plot details from both the book and the movie. If you have not finished either, skip ahead.

The novel opens with the death of Morgan's husband Chris and Clara's father in a car accident, alongside Jenny—Clara's aunt and Morgan's sister. The film keeps this tragedy as the inciting event but moves quickly through the funeral and immediate aftermath. In the book, more time is spent on Morgan discovering Chris's affair with Jenny, which adds layers to her grief. The movie hints at the betrayal but does not linger on it the way the novel does.

One of the book's central tensions is the mother-daughter conflict over Jonah Sullivan, Chris's best friend who steps in to help the family after the accident. Both Morgan and Clara develop feelings for him. The movie keeps this dynamic but condenses the timeline of their relationships. In the book, the emotional buildup is slower, with more internal monologue from both Morgan and Clara. The film relies more on visual storytelling and dialogue to convey the same tension.

The ending of the book allows both Morgan and Clara to find closure and move forward. The movie follows a similar resolution but streamlines the final act. Some secondary characters are less developed in the film, and certain scenes that provide emotional context in the book are either shortened or cut entirely.

If you read the book first, the movie will feel familiar but faster. If you watched the movie first, the book will give you more time inside the characters' heads and more backstory on what led them to this point.

Should you read the book after the movie?

If the movie worked for you, the book will give you more. More time with the characters. More context for the choices they make. More emotional weight around the grief and betrayal that drive the story.

Colleen Hoover writes with internal monologue that a film cannot fully replicate. The novel lets you hear what Morgan is thinking as she processes the affair, what Clara is feeling as she navigates first love while grieving her father. The movie shows you their actions. The book shows you why.

If you watched the movie and thought the mother-daughter conflict felt rushed or the romance felt underdeveloped, the book addresses that. The pacing is slower, the emotional arcs are deeper, and the secondary characters get more room to exist.

That said, if you watched the movie and it did not land, the book is more of the same. It is not a genre shift or a different story. It is the same story with more pages. If the premise did not work for you, reading the book will not change that.
