What do you think about the Enola Holmes movie?

Millie Bobby Brown produces and stars in Netflix’s adaptation of Nancy Springer’s book series Enola Holmes. Also starring Henry Cavill, Helena Bonham Carter, and Sam Claflin, the film follows the misadventures of Sherlock Holmes’ bright younger sister Enola as she comes into her own as a budding detective. It’s a smart, feminist twist on a classic, packed with fun and suspense. Here’s hoping for a second installment soon.

Enola is Sherlock’s younger teenage sister, and just like her big bro, she’s also into solving mysteries. She loves reading, she’s super smart, and she’s really close with her mom… so it makes sense that, after her mom goes missing, she’s more motivated than ever to do a little detective work herself. Her brothers, Sherlock and Mycroft, are also in the movie —obvs— though Mycroft existed in the Sherlock canon going all the way back to the original Sir Arthur Conan Doyle stories.

Enola didn’t just come out of nowhere, and she wasn’t a creation of Netflix, either. Enola Holmes is actually based on a YA mystery series written by Nancy Springer called The Enola Holmes Mysteries. They include different characters and themes borrowed from the classic Sherlock stories to create Enola’s world, and the series starts the same way the movie does: With her mother’s disappearance.
