The Better Sister: Did the Show Fix What the Book Couldn't?

Two estranged sisters. A dead husband they both have history with. A teenage boy who may or may not have killed him. The Better Sister by Alafair Burke is a psychological thriller about what women hide to survive and how far they'll go to protect the people they love. The Prime Video adaptation dropped in May 2025 with Jessica Biel and Elizabeth Banks, and we had a lot of thoughts, not all of them the same.

The book is mostly Chloe's perspective. She's a New York magazine editor with a controlled exterior and a life that looks perfect until her husband turns up dead. There are a handful of chapters from the detective on the case, but you're mostly in Chloe's head, working with whatever she decides to tell you. It also means you never really get Nikki, the older sister, the one in recovery, the one who shows up and ignores the hotel Chloe already booked and just starts putting her stuff down. Nikki is who all three of us actually liked, which is a problem because the book barely gives her room to be anything other than Chloe's version of her.

The Show

The show fixes that. Getting out of Chloe's head is the biggest structural change, and it pays off. There's a backstory reveal about what Adam actually did to Nikki that the book implies but the show puts on screen. Michelle said it made her feel gutted for Nikki in a way the book never got to.

What wasn't unanimous: Elizabeth Banks. Laura could not buy her as someone who had struggled with addiction. "She's too good at all of life." Michelle thought she nailed it.

The show adds a full storyline for Nikki that isn't in the book, and we disagreed on whether it worked. Katya defended it. Michelle and Laura weren't sold. The show also has characters literally seeing and talking to people who are dead. Katya and Laura found it unnecessary. Michelle thought it was the only way to show how haunted Nikki actually was. And Laura got bored somewhere in episodes four through six, which with eight episodes is a problem.

Book vs. Show

Two votes for the show, one for the book, and the book vote made a real argument. The mystery hits differently when you're stuck in Chloe's head and can't fully trust what she's telling you. The show gives you more. Whether more is better depends on what you wanted.

Ratings landed between three and four and a half. Laura described it as possibly a good nap show and we're choosing to take that as a compliment to the pacing.
