The “Enola Holmes” movies have done nothing so much as chart Millie Bobby Brown’s evolution from child actor to movie star. She was 16 when the first “Enola Holmes” debuted in 2020. As “Enola Holmes 3” arrives on Netflix, she’s 22. And all three movies have been driven by Brown’s natural charisma. The first two were directed by Harry Bradbeer, a veteran of “Fleabag,” and they delighted in her breaks of the fourth wall. “Enola Holmes” runs on her asides, glances and eyebrow raises.Everything else in these tales of Sherlock Holmes’ younger sister can be a bit over-amped and over-stylized. But “Enola Holmes 3,” like the two previous chapters, is spirited and fleet of foot, and, crucially, doesn’t take itself too seriously. When Enola’s mother, Eudoria (a scene-stealing Helena Bonham Carter) turns up and pronounces, “This is all a ridiculous merry mess,” she pretty well nails it.

If the first two “Enola Holmes” films leaned more Y.A., with a light feminist bent, the third film is a touch more grown up, leading Brown’s character closer to rom-com territory. In the movie’s opening scene, she hesitates about her imminent marriage to Lord Tewkesbury (Louis Partridge) before rushing by carriage to the wedding.
