Directors love Wagner’s operas, which infuse the suggestive sketchiness of parables into clearly conceived plots and characters. They offer both strong bones and flexibility.

“Lohengrin,” about an anxious and divided society into which arrives a figure with magical powers and secrets, has recently been placed in settings as varied as a laboratory, a classroom and a neo-fascist town square.

And, on Sunday at the Metropolitan Opera, in a dark, blunt mixture of pre-modern and post-apocalyptic elements. Directed by François Girard, the production suffers from a facile children’s-theater color scheme, but boasts a shining musical performance from the orchestra and the two leading singers.

At the Met in 1998, Robert Wilson distilled “Lohengrin” into a vision of hovering bars of light and glacially shifting gestures. The opening night audience, used to hyper-naturalistic Wagner productions, rebelled with a storm of boos. But 25 years later, the Wilson staging seems like an ahead-of-its-time landmark, a harbinger of how the company’s dramatic range would broaden.

Among the highlights of this new era has been Girard’s staging, from 2013, of Wagner’s “Parsifal.” Set on a stark hillside among a group of men in white button-ups and black pants, this was a take on the opera’s protectors of the Holy Grail as a contemporary cult over which planets loomed and orbited in projections.

Those cosmic projections have returned in Girard’s “Lohengrin,” with a kind of catastrophic heavenly explosion depicted during the orchestral prelude. The action that follows begins under a blasted wall that hangs at an angle over the stage, a huge hole open to a view of morphing stars and galaxies.

The people who enter are dressed in early medieval robes and heavy jewels; a pagan throne is formed from tree roots. But the wall is made of reinforced concrete, and Lohengrin, the mystical knight who soon arrives to avenge the honor of a woman accused of killing her brother, is wearing the spare modern-day outfit of the Grail defenders in Girard’s “Parsifal.”

The connection makes some sense: As we learn at the end of “Lohengrin,” when its title character’s secrets are revealed, Lohengrin is Parsifal’s son. But Girard’s nod to his “Parsifal” doesn’t do his new production any favors. While that “Parsifal” was revelatory in imagining the opera’s climax as the integration of women into the Grail cult, this “Lohengrin” isn’t interested in fresh interpretations. No one will mistake it for a landmark in Met history.

Instead, Girard’s “Lohengrin,” which brings the opera back to the company after 17 years, is an emphatic, serviceable, basically conservative framework for the piece. Thankfully, some superb singers fill the frame. Most important, almost floating through the staging with uncanny serenity and dignity, is Piotr Beczala in the title role.

This square-jawed, always stylish tenor is best known at the Met for playing dashing men in French and Italian classics, like the Duke in “Rigoletto,” Rodolfo in “La Bohème” and, this winter, the ardent Loris in “Fedora.” But the clearest precursor to his melancholy Lohengrin is his Lensky in Tchaikovsky’s “Eugene Onegin,” who sings with wintry loneliness as he prepares to duel and die.

Beczala performs the Wagner role — pure, precise and often treacherously exposed — with total security and elegance. The soft passages have fairy-tale delicacy; his outpourings, a robust plangency reminiscent of his more extroverted roles. But this Lohengrin, even at his most passionate, has the proper coolness of an otherworldly figure. He is human, but not entirely.

There is also an intriguing coolness when we meet Tamara Wilson’s unjustly accused Elsa, a glassy sheen to her tone as icy-blond as her hair. But while Beczala’s Lohengrin maintains his reserve, Wilson’s voice gradually warms, gently molten in their love duet and palpably angry in confrontation.

Yannick Nézet-Séguin, the Met’s music director, conducts this grand score with a sure sense for the elasticity of pace that makes Wagner’s scenes breathe. He led the orchestra on Sunday in broad expansions before focusing it back into tumbling momentum. The shimmering start of the prelude to Act I was fragile without being wispy, building with lyrical flow to a stirring climax.

There are onstage trumpets in this opera, and extra brass forces in the balconies. But Nézet-Séguin kept the textures light; even at its mightiest, the sound was never stolid.

Changing shirts between the acts, from black to red to white, he also underlined the already obvious play with color that is all too central to the staging. The choristers manipulate complicated sets of magnets in their robes to reveal red, green or white linings, depending on the dramatic needs of the moment. (The sets and costumes were designed by Tim Yip, an Academy Award winner for “Crouching Tiger, Hidden Dragon”; the gloomy lighting, by David Finn; the interstellar projections, by Peter Flaherty.)

Green symbolizes King Heinrich, who has arrived in Brabant (around Antwerp in present-day Belgium) with his followers to rally the people there to join him in fighting off a coming invasion from the east. Red is the color of the native Brabantians, who are under the sinister influence of Friedrich von Telramund and his wife, the sorceress Ortrud. And white evokes the innocence and purity of Elsa, to whose aid Lohengrin has come.

Fine, if rather on the nose. But the endless flashings of the different linings on the beat of musical flourishes — and the visible struggles that some choristers on Sunday had with the magnets — grew tiresome.

And must every Met production now have bits of choreographed slinking and twirling? Here, credited to Serge Bennathan, were lightly dancing attendants with lanterns, heads-thrown-back courtiers, whirling nobles and laughably in-time marching. It was all of a piece with a production that’s straightforward to the point of eye-roll overstatement.

As Ortrud, the soprano Christine Goerke was perhaps the performer closest to the mood of the staging: She’s unsubtle, if effective, constantly wringing her hands and gripping her necklaces. Girard strands her alone, making over-the-top witchy gestures, for almost the whole of the Act III prelude. We get it: She’s evil!

Goerke’s voice has vigor, but rich phrases alternate with sour, snarled ones; some high notes shiver, while some just miss the mark. The bass-baritone Evgeny Nikitin, an imposing presence, sounded weary and out of tune as Telramund. I found myself wishing that the baritone Brian Mulligan, who sang the Herald with unusually vivid intensity, had that larger part instead. The bass Günther Groissböck was a forceful Heinrich.

The Met’s chorus, in one of the most difficult works in its repertory, was both stentorian and evocative: In the awe-struck passage after Lohengrin introduces himself, its ethereal singing was almost more felt than heard. Only in some of the most complex counterpoint could the sound have been crisper, the words sharper.

Girard’s staging is more lucid than his murky take on Wagner’s “Der Fliegende Holländer,” which will be revived at the Met this spring. It does, at least, convey the urgency of the march toward war that gives the opera its stakes. And this production will always be an unintentional memorial to the Russian invasion of Ukraine.

Conceived as a co-production of the Bolshoi Theater and the Met, it premiered at the Bolshoi in Moscow on Feb. 24, 2022, the day of the invasion. Soon it became clear that sharing the production would be impossible, and that the sets would have to be rebuilt from scratch, adding over $1 million to the show’s cost.

“Lohengrin” is an opera with war on its mind. But King Heinrich and his call to defend Germany against invaders don’t make for an easy parallel with the besieged Ukraine and its president, Volodymyr Zelensky.

That is because Heinrich’s story was taken up — by Wagner and, later, by the Nazis — as a symbol of pan-Germanic nationalism, with all its darkness and xenophobia. That is the context in which a few opera companies have changed a word in Lohengrin’s final line, when he declares, at the magical return of Elsa’s brother, that the people’s “Führer,” or leader, has arrived.

To further avoid the associations of this savior figure with Hitler, many directors offer a comment in how they depict the brother. Is there something ominous about him? Something redemptive? Anything?

Girard, though, has a very Aryan-looking, blond young man in flowing, angelic white come down the stairs, a final odd bit of naïveté in this “Lohengrin,” a production that ends up being too simplistic for a complex moment and a complex opera.
