Enola Holmes grows up: how Philip Barantini turned a YA sleuth into a Victorian-era coming-of-age

The summer of 2026 has been quietly kind to the British detective on screen. After the rural charms of the BBC's "Sheep Detectives," Netflix has now delivered the third film in its Enola Holmes franchise, with Millie Bobby Brown returning as Sherlock's younger sister and Philip Barantini — fresh off the HBO limited series "Adolescence" — taking over directing duties from Harry Bradbeer. Variety's review, published on 30 June 2026 at 23:00 UTC, calls the result "frisky and grown-up," and the description lands harder than the usual sequel-bumpf.

That a YA-lit sleuth is being steered, two films in, toward adult register says as much about Netflix's franchise maths as it does about the actress now fronting it. The streamer wants the property to age with its audience. Barantini — whose previous work has leant hard into working-class masculinity and kitchen-thriller tension — is exactly the wrong résumé on paper and exactly the right one in practice.

What changes when Barantini takes the wheel

Bradbeer's two Enola films were polished, brightly lit, and respectful of the source novels' teen-magazine cadence. They were also, by the end, beginning to repeat themselves — period set-pieces, VFX-heavy action beats, Henry Cavill's Sherlock increasingly a guest star. Barantini's instinct, judging by Variety's read, runs the other way: moodier lighting, less reliance on the film's visual-effects budget, more attention to the actress's face and posture than to the surrounding diorama. The Variety review credits him with producing a film that feels "grown-up" rather than merely older.

The practical effect is a tonal shift that studios usually resist in the middle chapter of a working franchise. Brown is now twenty-two, and the screenplay — by Jack Thorne, the same writer as the first two films — appears willing to let Enola act her age: a young woman exiting adolescence, not a child playing dress-up as one. Variety frames it as the film finally catching up to its star.

The summer-of-the-British-gumshoe pattern

It is worth pausing on the timing. "Sheep Detectives" arrived earlier in the summer to generally warm notices, and the Variety review explicitly positions "Enola Holmes 3" in conversation with it: a season in which cosy, low-stakes British detective stories are doing solid business for both linear broadcasters and streamers. The structural read is straightforward. With superhero fatigue biting into the franchise economics of the major US platforms, mid-budget, character-driven genre pieces — a Holmes, a village mystery, a cosy crime — are doing the work that comic-book tentpoles used to.

For Netflix specifically, this matters. The streamer has spent two years trimming its film ambitions away from the four-quadrant action originals that defined its late-2010s slate. A mid-budget Holmes with a built-in fanbase is exactly the kind of property its new economics rewards: a known title, a returning cast, a director with recent prestige credit, and a budget that does not depend on a $200m opening weekend to clear.

What the franchise keeps — and what it discards

The third film's choices are more revealing than the review lets on. Keeping Jack Thorne as writer preserves continuity of voice; promoting Barantini over Bradbeer signals that the property's visual language is meant to change. Brown remains the producer through her company, PCMA Productions, which Variety notes is part of a wider pattern of actor-producers tightening their grip on star-driven franchises.

What is being discarded, at least in this instalment, is the sense of Enola as a child operative moving through an adult world. The "frisky and grown-up" framing implies a film more interested in the protagonist's interior than in the puzzle-box mechanics of the first two films. Whether that trade works commercially will not be clear until Netflix releases viewing figures, which it typically does not for mid-tier originals.

Stakes and the road to a fourth film

The franchise question is whether this tonal reset holds. Netflix has historically been ruthless about pulling the plug on originals whose second-and-third-film curves disappoint, regardless of critical reception. A successful third film — even one that splits the fanbase between those who liked the YA brightness and those who prefer the moodier register — almost certainly guarantees a fourth. A middling one, on the other hand, gives the streamer the cover it needs to let the property rest.

For Brown, the calculation is different. She is two years past "Stranger Things," the role that made her a global name, and visibly building a post-Hawkins career around producing and starring in projects she controls. A Holmes film that ages with her — and that gives her room to be twenty-two rather than seventeen — is, in industry terms, more useful than a successful one that does not.

For Barantini, the assignment is reputational rather than commercial. He came up through gritty British realism — "Boiling Point," the single-take kitchen drama, and the "Adolescence" limited series — and a Victorian Holmes film with broad commercial appeal is, on paper, an odd fit. Variety's review suggests the mismatch is the point: a director who has built a career on intensity inside small spaces now applying that intensity to a franchise budget.

What remains uncertain

The Variety review is one critic's read, and a positive one. The question of how the tonal shift lands with the existing audience — younger viewers who came in for the first film in 2020 and have since grown up alongside Enola — will not be answerable until the film has been out for a few weeks. Netflix does not break out viewing data by demographic for originals of this size, so the audience verdict will arrive indirectly, through social-media sentiment and renewal signals, rather than through any clean metric.

The broader industry pattern — cosy British crime doing the work that superhero films used to do — is also a summer-of-2026 read, not a settled structural shift. One season's slate does not remake a studio economy. It does, however, mark where the money is currently comfortable going, which is the only signal streamers actually trade on.

Desk note: Monexus is reviewing this film from the Variety review alone; the outlet's verdict is treated as the wire read of record, not as endorsement. The structural framing — franchise economics, tonal reset, the cosy-British-crime summer — is editorial analysis drawn from the same review and from Monexus's standing read of Netflix's film slate over the past two years.
