Enola Holmes 3 arrives on Netflix with new questions about the streaming era's middle-aged franchise

The third entry in Netflix's Enola Holmes series arrives this week carrying an awkward double burden: it must justify a film franchise inside a company that has been quietly pulling back on them, and it must do so with a young star who is, by the standards of a long-running series, growing up in public. The Guardian's review published on 30 June 2026 finds a film that is "often thoughtful yet ultimately lesser" — a verdict that, taken together with the reviewer's notes on structure and pacing, captures a problem that is no longer just Millie Bobby Brown's.

Three films is, for most Netflix originals, an achievement. The streamer has built its brand on cancelling things at the cliff edge; the fact that Enola Holmes is reaching a third entry at all is evidence of a property that has done something unusual for the platform. The question the review raises — softly, almost in passing — is whether the third film is also a sign that the franchise has hit the point where iteration starts to cost more than it returns.

What the review actually finds

The Guardian's Charles Bramesco writes that the new film returns Brown, the creative team behind Netflix's recent limited series Adolescence, and the core premise of the Holmes family in 1880s London. The verdict is mixed: a review that praises the film's instincts on period detail, gender politics and the byplay between Brown and her older co-stars, while faulting it for an overstuffed plot and a mystery whose pieces do not quite lock together. The phrase "losing steam" is doing real work in the headline — it is the conclusion of a reviewer who has watched the series grow up alongside its lead.

The structural complaint, more than any individual scene, is what makes the review worth reading for anyone tracking Netflix's pipeline. Three mysteries in, the series has to keep finding bigger locks for the same key. The first film had the virtue of discovery; the second had the virtue of escalation. The third, the reviewer suggests, has run out of small rooms to escape from.

The Adolescence factor

The most interesting production fact in the Guardian's write-up is the credit to the team behind Adolescence — the British limited series that became, against most predictions, one of Netflix's most-discussed originals of 2025. Bringing that room onto a feature-length film franchise is not, in itself, a sign of trouble; it is a sign of a streamer trying to keep a hit-making ensemble together. It also illustrates the unusual shape of Netflix's production economy: a company that can move the people behind one breakout onto a sequel of a different property, in the hope of cross-pollinating attention.

That cross-pollination cuts both ways. The Adolescence team is associated, in the public mind, with the kind of contained, single-sitting drama that streaming audiences treated as an event. A threequel to a YA-leaning franchise is a different kind of object. The Guardian's review senses the mismatch without quite naming it as a cause of the film's unevenness.

What the franchise problem actually is

The "middle-aged franchise" is a real category in modern Hollywood, and it does not just describe superhero films. It describes any series that has outlived the cultural moment that produced it. The first Enola Holmes was released in 2020, when Netflix was still the default destination for a particular kind of mid-budget, star-driven feature. The second came in 2022, when the streamer was beginning to make different bets. The third arrives at the end of June 2026 against a backdrop in which the company has spent the intervening years restructuring its film division, narrowing its release strategy, and getting out of certain kinds of deals that the original Enola Holmes depended on.

A reviewer can only respond to the film in front of them, and Bramesco's verdict is clearly about craft as much as context. But the timing of the third film — the moment at which it arrives, the streamer it arrives on, the audience it is asking to come back — is part of the story. The Guardian's "losing steam" is, read closely, a verdict on a property and on a moment.

Counter-read: the film may be a victim of its own success

There is a plausible alternate reading. Netflix's Enola Holmes franchise is, by the metrics that matter to the company, a success: three films, sustained cast, durable brand association with a young star. If the third film is the weakest of the three, that is also a description of a series that has not collapsed between entries. Plenty of YA-leaning franchises have not made it to a third film at all. A lesser threequel is, in that framing, the price of having a threequel at all.

The Guardian's review does not contradict that reading so much as qualify it. The film is watchable, the cast is committed, the period detail is sound. What is missing, in Bramesco's account, is the sense that the material has anywhere new to go. The mystery, in other words, is the problem: not the production, not the cast, not the streamer, but the small engine of the plot itself.

What remains uncertain

The review does not, and cannot, settle the commercial question. The Guardian does not publish viewing figures, and Netflix's internal numbers are not public in a form that would let an outside reader compare the third film's reach with its predecessors'. Whether the film is a quiet underperformer, a respectable mid-tier release, or a genuine hit will not be clear for weeks. The critical response is the first data point; it is not the last.

What the review does do, more usefully, is frame the question that Netflix's film strategy will be answering all through the second half of 2026: whether the streamer still knows how to grow a tent-pole. The Enola Holmes series was once part of the answer. The third film, on the evidence Bramesco lays out, is no longer obviously part of it.

This publication reads the Guardian's verdict as a modest negative — a franchise doing its job competently while the streamer around it recalibrates. The interesting story is not whether Enola Holmes 3 is good or bad, but what its reception tells us about the kind of films Netflix is still willing to make.
