Minneapolis native Yara Shahidi shines in 'The Sun Is Also a Star' despite its dull script

Teenagers need melodrama. They always have. Big, sweeping emotions are seemingly the only things that can match the high-stakes, hormone-enhanced feelings experienced by teens. Director Ry Russo-Young excels at rendering those emotions with a singular sense of artfulness, which she demonstrated in "Nobody Walks."

In "The Sun Is Also a Star," Russo-Young swirls together sun-dappled selfies, luscious skin, urban grittiness and hip-hop beats, the aesthetics perfectly matched to emotion. She creates a heady, knee-buckling mood that nearly conceals the weaknesses in story and performances.

The film is an adaptation of Nicola Yoon's second novel. Her first book, "Everything, Everything," also became a movie. It starred Amandla Stenberg and Nick Robinson in a swoony tale about a quarantined girl who falls in love. The sick teen genre is a well of deep potential with its heightened stakes and ticking clock.

This is worth mentioning because, in the structural sense, "The Sun Is Also a Star" is also a sick teen movie — without sickness. But the stakes are high and the clock is ticking, in this case on a mandatory deportation from the United States.

Minneapolis native Yara Shahidi (of TV's "Black-ish" and "Grown-ish") stars as Natasha, the daughter of Jamaican immigrants but a New Yorker through and through. The day before her family is set to be deported back to Jamaica, she makes a last-ditch attempt to change their fate by pleading their case to an immigration lawyer.

She's spotted in Grand Central Station by Daniel ("Riverdale" star Charles Melton), who notices she's staring at the starry ceiling, and he interprets her "Deus Ex Machina" jacket as a sign. Daniel is a poet, a dreamer and believer in destiny, and he takes off after her.

After he saves her from a speeding BMW, he persuades the science-driven Natasha to spend some time doing the "36 Questions" love study from the New York Times. "Give me a day," he says, "and you'll fall in love with me."

But then, they open their mouths and the spell is broken. The dialogue (the script is by Tracy Oliver, co-writer of "Girls Trip") just grinds things to a halt, with speeches that are a bit too on the nose and too-grand declarations of love. Then again, all those things seem so profound and meaningful at that age.

As pretty as Shahidi and Melton are, they don't share a palpable chemistry. Shahidi is undoubtedly a star, and while Melton is charming and has a goofy puppy-dog energy, the more dramatic moments demonstrate the upper limitations of his range. Shahidi's few short scenes with immigration lawyer John Leguizamo are far more riveting.

The shortcomings are somewhat covered up by Russo-Young's impressive filmmaking. A New York City native, she captures the arresting energy of the city while imbuing the film with a sense of lyricism and grace, as if the streets are sprinkled with magical fairy dust. The world looks the way it feels when you're falling in love, like everything is at its best, and everything makes sense.
