Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.

A lot or a little?

What's the story?

From Luther creator Neil Cross comes THE SISTER, a British crime thriller about a missing girl and a man tormented by a dark secret. Party goer Elise Fox (Simone Ashley) goes missing, and seven years later Nathan Redman (Russell Tovey) is married to her sister, Holly (Amrita Acharia). But when an old acquaintance named Bob (Bertie Carvel) shows up at their home one rainy evening, Nathan realizes that the secret he's kept from his wife and her family about Elise’s death is about to be exposed, and their lives will be destroyed. 

Is it any good?

This dark mini-series offers a psychologically disturbing narrative that slowly uncovers the details about Elise’s mysterious death, and Nathan’s role in it. Flashbacks are used to reveal the events leading up to Nathan and Bob’s meeting, allowing viewers to see what led up to that moment and to understand the significance of the later plot twists. 

There are some suspense-filled moments, but the overall series feels sluggish, thanks to the deliberately slow pacing of events occurring in real time. Additionally, the disturbing aspects of Nathan’s actions, which are central to the story, are never fully explored. As a result, The Sister creates an eerie, but uneven, viewing experience that leaves you feeling more frustrated than creeped out.

Talk to your kids about ...

  • Families can talk about Nathan’s actions over the years. What is the most troubling? Is there anything that justifies them?

  • What does the ending of the The Sister suggest about Nathan’s life going forward? Would you have ended the story this way?
