The Better Sister: Murder, Secrets, and an Open Ending

Prime Video’s 'The Better Sister' is a thriller based on Alafair Burke’s novel, following estranged sisters Chloe (Jessica Biel) and Nicky (Elizabeth Banks) as they reconnect after the murder of Chloe's husband, Adam (Corey Stoll), who was also Nicky’s ex and the biological father of Chloe's son. The story unravels family secrets and trauma, culminating in the revelation that Nicky stabbed Adam in self-defense while confronting him about his abuse of Chloe.

Critics have praised the series for its nuanced performances, particularly from Biel and Banks, and its subversion of genre conventions. The show is recognized for its exploration of flawed female characters, family dynamics, and its sophisticated take on crime drama.
