The quiet inscrutability of the movies of Flemish filmmaker Bas Devos can be gleaned from their reviews, filled with vague appreciations and words like “unassuming” and “placidity.”

Which is the viewer’s clue that the drama depicted is subtle in the extreme in festival darlings such as “Violet,” “”Ghost Tropic” and “Hellhole.”

The one funny thing that stands out about “Here,” his latest, is that one film festival nominated it for “best documentary.” It isn’t a documentary. It has actors playing characters, a hint of a love story, and a lot of Belgian urban and suburban scenery. But one can understand the confusion. Nobody — critics, festival curators or festival-goers, wants to give away that maybe they don’t “get it.”

“Here” is something of a reverie, with a cosmopolitan context. The Brussels and environs settings are seen as a gathering place for transplants — immigrants. A simple bus ride has the look of committee meeting at the U.N.

And that ties into the film’s organizing metaphor — moss. A Chinese immigrant, ShuXiu (Liyo Gong), studies the tiny plant and its reactions to a changing environment. There is “a whole forest of life” in every accumulated clump, she tells Romanian construction worker Stefan (Stefan Gota).

It is a simple life form, the first plant to establish itself on land, and it thrives seemingly wherever it finds itself. ShuXiu plucks a clump from between cracks in a city sidewalk.

That’s an immigration metaphor writ large, or what passes for one in the “passivity” of Bas Devos.

Stefan hangs with his co-workers, meets up with friends, all of whom are immigrants, some of whom are doing favors for him — fixing his worn out car, for instance. He makes them soup from his homeland.

And now there’s a work break and he’s got on his shorts in preparation for “going home,” where his mother awaits and she hopes he will visit a friend there who has somehow wound up in prison.

Stefan’s wandering has only the vaguest of aims. How and when is he leaving? He’s emptying his fridge in preparation. Will he be coming back?

“This is home,” he says to no one but himself as he takes in one urban construction site view.

He meets with his sister (Alina Constantin), a long-settled immigrant nurse. And then he gets caught in the rain and ducks into a Chinese restaurant. ShuXiu is behind the counter, friendly and outgoing. He has no clue that she’s merely helping her “auntie,” who runs “La Longue Marche,” a landmark event in the history of communist China and a curious name for an eatery.

Stumbling into her on a forest shortcut he sometimes takes, Stefan learns of her true profession and passion for it. Maybe he should postpone his trip and, you know, make her some soup.

“Here,” which has little dialogue (in French, Flemish, Chinese and Romanian), isn’t a tale with action or many of what you’d call basic dramatic devices. It meanders, broods, and takes a shot at entrancing us with its vibe and passivity. Nothing much happens because no one is driven to make much happen.

Yes, it’s rather dull, with little here that could be confused for “entertaining,” and pardonnez moi for suggesting that “The Emperor has no clothes.”

But it’s interesting enough as it invites the viewer into interpretations, messages it might be sending and observations Devos is making about our changing world and those best adapted to roll with those changes, taking comfort and pleasure wherever they settle and accumulate. Like moss.
