Aiming to give a family-friendly but feminist twist to the mythos of Sherlock Holmes, Enola Holmes offers a teen heroine who complains about corsets and solves puzzles as well as any genius man! Led by Millie Bobby Brown, it’s an earnestly spirited endeavor that offers a rollicking pace, colorful costumes, jaunty montages, and sparking stunts. For kids, it’ll probably be a welcomed bit of thrilling fun. For parents, it can be a worry-free diversion. Still, it’s a shame the filmmakers didn’t strive for something richer or challenging. In the end, Enola Holmes’ lack of depth suggests they think their audience isn’t clever enough to crave something more.
