A successful media executive, her estranged sister, and the man who married them both drive the conflict in Prime Video’s The Better Sister.
The thriller follows Chloe Taylor as her controlled life falls apart after her husband, Adam, is found dead.
Many The Better Sister reviews praise Jessica Biel and Elizabeth Banks, whose tense chemistry strengthens the familiar murder mystery.
Here is a spoiler-light look at the story, performances, reactions, and whether the eight-episode series is worth watching.
The Better Sister Review at a Glance
The Better Sister works best as a family drama disguised as a murder mystery.
Its investigation supplies the suspects, secrets, and episode-ending revelations, but the strained relationship between Chloe and Nicky gives the series its real pull.
Jessica Biel plays Chloe with convincing restraint, while Elizabeth Banks brings sharper humor and emotional volatility to Nicky.
Together, they make years of resentment and reluctant affection feel believable.
The series is easy to binge, especially during its opening episodes, but some revelations take too long to arrive, and several thriller conventions will feel familiar to regular viewers of the genre.
What is “The Better Sister” About

The Better Sister follows Chloe Taylor, a successful magazine editor whose ideal life collapses when her husband, Adam, is murdered.
The investigation reunites Chloe with her estranged sister, Nicky. She is also Adam’s former wife and Ethan’s biological mother.
As family secrets surface, the sisters must confront years of resentment and decide if they can trust each other.
Soon, the case becomes about more than Adam’s killer. It raises a deeper question: How well did either sister truly know him?
Why The Better Sister Works So Well as a Crime Drama
Strong lead performances, tense family conflict, and steady suspense help The Better Sister rise above its familiar murder-mystery setup.
Jessica Biel and Elizabeth Banks Make the Series Worth Watching
Jessica Biel and Elizabeth Banks create much of the show’s tension. Biel plays Chloe as guarded and image-conscious, while Banks makes Nicky blunt and emotionally open. Their chemistry keeps viewers unsure which sister to trust.
The Sisterly Conflict Is Stronger Than the Murder Mystery
The deeper mystery is why Chloe and Nicky became estranged. Their opposing values and harmful choices, often made to protect Ethan, keep the title’s central question open: Who is truly the better sister?
The Series Keeps Viewers Watching
The early episodes build suspense through changing suspects, flashbacks, and new details about Adam. Most episodes reveal information that changes earlier events, making the series easy to binge despite some uneven pacing.
The Supporting Cast Strengthens the Story
Kim Dickens, Bobby Naderi, and Gloria Reuben add weight to the investigation and courtroom scenes. Through flashbacks, Corey Stoll also turns Adam from a murder victim into a more complicated figure.

Where the Better Sister Falls Short?
Strong performances keep The Better Sister watchable, but the series does not fully escape the weaknesses of its familiar setup.
- The story feels familiar: The wealthy family, murdered husband, hidden affairs, and public scandal follow common domestic-thriller patterns.
- Eight episodes feel too long: The middle episodes repeat conflicts and delay key answers, weakening the early momentum.
- The tone is uneven: Shifts between family trauma, courtroom drama, and dark comedy do not always feel natural.
- Some twists feel forced: Several revelations rely on convenient timing or exist mainly to create cliffhangers.

Reviews of The Better Sister range from positive to mixed, with critics and viewers often agreeing on its strongest performances while differing on pacing and twists.
| Group | Overall Opinion | Common Praise | Common Criticism |
|---|---|---|---|
| Critics | Mixed to positive | Jessica Biel and Elizabeth Banks, family tension, murder mystery | Slow pacing, familiar ideas, uneven twists |
| Viewers | Generally warmer | Strong chemistry, secrets, cliffhangers, binge-worthy story | Midseason slowdown, frustrating choices, predictable moments |

Is The Better Sister Worth Watching?
Watch The Better Sister if you enjoy character-led murder mysteries, complicated sibling relationships, family secrets, and courtroom drama.
You may want to skip it if you prefer fast-paced crime stories, detailed police work, original mystery plots, or consistent pacing and tone.
Will There Be a Second Season of The Better Sister?
Prime Video has not confirmed a second season of The Better Sister. The show was released as a limited series, and its main murder mystery reaches a clear resolution in the finale.
Jake’s unexplained death does leave room for another story involving the Gentry Group, Michelle Sanders, or the surviving sisters.
But for now, viewers should treat The Better Sister as a one-season thriller rather than a continuing series.
The Bottom Line
The Better Sister succeeds because it treats the murder as the beginning of a family reckoning, not the entire story. Jessica Biel and Elizabeth Banks deliver compelling performances.
As noted across many The Better Sister reviews, the show loses some force through slow pacing, familiar thriller devices, and convenient late developments.
Still, it remains an engaging weekend watch for fans of family secrets, shifting loyalties, and character-led crime dramas.
The mystery may bring viewers in, but Chloe and Nicky’s damaged relationship gives them a reason to stay.
