The bare minimum you expect from a sleuthing action comedy of the “Anybody Named Holmes” variety is that it hold your interest. Netflix’s “Enola Holmes 3” falls short of even that low bar.

It’s got a wedding and a few kidnappings, suspects chased and caught just in time to be shot, the ugly consequences of British colonialism and the sunwashed sights of scenic, cinematic Malta to recommend it.

And none of it amounts to much of anything more than Millie Bobby Brown narrating narrating narrating her latest “Enola” tale, and turning to the camera when she hears the words “Ernest Augustus” and quipping, “He has a first name,” about the man she is set to marry. “I was surprised, too!”

It begins messy, with a cryptic prologue that leaps into a wedding to the too-pretty-to-marry rich and idealistic swell Tewkesbury (Louis Partridge) that just isn’t. And as it bounces back and forth between kidnappings — brother Sherlock (Henry Cavill) among them — codes and clues and treasure, “Enola 3” never adds up to anything more than worn out genre tropes, cliches and lazy dialogue anachronisms like “stuck on ‘repeat,” a phrase that best describes this film series at this point.

Even the most interesting Moriarty in ages can’t save it, and even “she” is scripted in flat, superficial strokes.

Young social justice crusader Lord Tewkesbury asks our sleathing younger sister to Sherlock to marry him, and as his parents wed in Malta, they’re off. But once there, Sherlock’s sniffing around gets him snatched and Enola and Dr. Watson (Himesh Patel) dash off to find him.

Advice about looking beyond the surface of things is added to Enola’s grab back of :”advice” and detecting skills.

“Dr. Watson, what would my BROTHER do?”

A comical anti-imperialist Maltese revolutionary (Joe Azzopardi) plays a vaguely Pythonesque/Patinkin in “Princess Bride” role in their exploits, arriving and always introducing himself, his revoliutionary group and their “goals” in ending the rule of the Britsh crown.

But laughs are few and excitement impossible to conjure up in this Philip Barantini film.

When Ms. Brown signed her long-term deal with Netflix, surely she was hoping for more than just a short-term franchise gig to replace “Stranger Things.” She and Netflix have run out the string on this, and all she has to show for it is a shot at working with the director of “Villain” and “Boiling Point.”

Despite her early promise, her window to stardom was always narrow, and now it’s closing.

We’d love to think Helena Bonham Carter, still classing up the joint and bringing a dab of sparkle to the attempts at wit as Enola’s feminist revolutionary mum, would give us the best one-line review of this latest and probably last “Enola” outing.

“This is all a ridiculous merry mess!”

But no. “Merry” never enters into it.
