You know that feeling when you start a show just for background noise and suddenly it's 3:00 AM and you’re screaming at your TV? That's the vibe with The Better Sister TV show. It’s messy. It’s polished. It’s exactly the kind of high-stakes domestic noir that Prime Video has been perfecting lately. Honestly, if you liked Big Little Lies or The Undoing, this is going to be your next entire personality for a weekend.
The series is based on Alafair Burke’s 2019 bestseller. It’s got that classic "did she or didn't she" energy, but it’s anchored by two powerhouses: Jessica Biel and Elizabeth Banks. They play sisters Chloe and Nicky. They haven't talked in years. Then, Chloe’s husband—who just happens to be Nicky’s ex-husband—gets murdered.
Yeah. It’s that kind of drama.
What is The Better Sister TV Show actually about?
Let's break down the setup because it's a lot. Chloe (Biel) is the "perfect" one. She’s a powerhouse editor, has the gorgeous house, the successful husband Adam, and the teenage son. She’s got it all together. Or she wants you to think she does. On the flip side, you have Nicky (Banks). She’s the "mess." Recovering addict, struggling, and perpetually living in Chloe's shadow.
The kicker? Adam was Nicky’s first. He left the "messy" sister for the "perfect" one.
When Adam is brutally killed in their family home, the police start looking at everyone. The investigation drags all those old skeletons out of the closet. We aren't just talking about a murder mystery here. It’s a deep, sort of painful look at how siblings compete, how they betray each other, and how memory is a lying dog.
You’ve got showrunner Olivia Milch at the helm. She worked on Ocean’s 8, so she knows how to handle a female-led ensemble with a bit of bite. The show doesn't just stick to the "who killed Adam" plot. It dives into the gendered expectations of being a "good" woman versus a "bad" one.

Why the casting makes or breaks it
Casting Jessica Biel was a smart move. She’s basically the queen of the prestige thriller now after The Sinner. She has this way of looking totally composed while you can see her pulse jumping in her neck. It’s stressful to watch. In a good way.
Elizabeth Banks is the real surprise for some. We’re used to her being funny or high-fashion (shoutout to Hunger Games), but here she’s raw. Nicky is a character who has been told she’s the "worse" sister her whole life. Banks plays that resentment with so much grit. You sort of want to root for her, even when she’s making terrible decisions.
Breaking down the Alafair Burke connection
If you haven't read the book, don't worry. The show stands on its own. Alafair Burke is a former prosecutor, so her writing always has this legal precision that makes the procedural parts feel real. She doesn't just hand-wave the law.
In The Better Sister TV show, that realism translates to the screen. The way the detectives interact with the family isn't just "TV cops" doing "TV things." It feels invasive. It feels like the walls are actually closing in on these women.
Interestingly, the show tweaks some of the pacing from the novel. A book can live in a character's head for 300 pages. A show needs momentum. The series leans harder into the visual contrast between the sisters' lives. You see Chloe’s sterile, glass-walled world versus the darker, more cluttered reality Nicky inhabits. It's visual storytelling 101, but they do it so well.
The "Domestic Noir" trend
We’ve seen a massive surge in this genre. Why? Because it’s relatable. Most of us aren't international spies, but most of us have a sibling or a complicated ex. The Better Sister TV show taps into that universal anxiety. It asks: How well do you really know the person sleeping next to you?

Key themes that keep you watching
It isn't just about the murder. Honestly, the murder is almost secondary to the psychological warfare between Chloe and Nicky.
- The Burden of Perfection: Chloe is drowning trying to keep up appearances. It’s exhausting to watch, which is the point.
- The Cycle of Addiction: Nicky’s struggle isn't glossed over. It’s a central part of why she’s distrusted, even when she’s telling the truth.
- Betrayal: Taking your sister’s husband? That’s a bell you can’t unring. The show explores if forgiveness is even possible in that scenario.
Is it worth the hype?
Look, TV is crowded right now. There are a million thrillers. But The Better Sister TV show stands out because it doesn't treat its audience like they're stupid. It expects you to keep up with the shifting timelines and the subtle clues hidden in the dialogue.
The cinematography is moody. It’s got that Pacific Northwest chill (even though it’s set in New York/Connecticut vibes). It makes you want to wrap yourself in a cardigan and drink wine while judging everyone on screen.
One thing people might find jarring is the pacing in the middle episodes. Like many streaming shows, it could have probably been a movie, but the extra runtime allows for better character development. You get to see the son, Ethan, deal with the fallout. His perspective adds a layer of "the sins of the parents" that gives the show more weight.
What critics are saying
Initial reactions have praised the chemistry—or lack thereof—between Biel and Banks. They don't feel like friends. They feel like people bound by blood who would rather be anywhere else. That tension is the engine of the show.
The New York Times and Variety have both noted that while the "dead husband" trope is well-worn, the execution here feels fresh because of the focus on the female bond. It’s not just about the man. He’s the catalyst, but the sisters are the story.

How to watch and what to expect
The show is a Prime Video original. If you’re planning a binge, clear about six to eight hours. You won't want to stop once the first major twist hits (usually around the end of episode two).
Don't go into this expecting a happy ending where everyone hugs. That’s not what this is. It’s a noir. It’s supposed to be dark. It’s supposed to make you feel a little bit uncomfortable about human nature.
Actionable steps for the best viewing experience
If you want to get the most out of The Better Sister TV show, follow this "pro-viewer" checklist:
- Watch the background: This show loves "deep staging." Sometimes the most important thing isn't what the character is saying, but what’s happening in the reflection of a window or in the doorway behind them.
- Read the book afterward: Alafair Burke’s prose is tight. Seeing how they adapted the interior monologues into visual scenes is a masterclass in screenwriting.
- Avoid spoilers: Seriously. Stay off Twitter/X hashtags until you're caught up. The final reveal is one of those that makes you want to go back and rewatch the whole thing immediately to see what you missed.
- Pay attention to the color palette: Notice how Chloe is often in whites and creams (trying to look pure) while Nicky is in darker, muddier tones. As the show progresses, these colors start to bleed into each other.
The series is a reminder that family is complicated, secrets are heavy, and sometimes, the "better" sister is just the one who hasn't been caught yet. If you're looking for a sharp, cynical, and addictive ride, this is it. No filler. Just straight-up suspense.
Watch it with someone you can gossip with afterward. You’re going to have thoughts about that ending. Trust me.
