But little by little, Amber is stripped of all the things that give her meaning and security. A harder, darker Amber emerges. “I have this under control!” she insists, as she postpones key meetings and works long hours at dismal jobs. (Tip your doughnut shop workers, folks.)

This alarms her motley crew of friends, including a maybe-boyfriend (a solid Rhenzy Feliz), her drama club teacher (an underused Fred Armisen) and a sour-outside-but-sweet-underneath nursing home resident (Carol Burnett, yes, that Carol Burnett, absolutely incapable of disappointing).

“You do so much for other people, but when you need just a little bit of help, you push us all away,” says the maybe-boyfriend. “What is so bad about needing help?”

There is a “Good Will Hunting” vibe to the film, a gifted young person sliding toward obscurity who is helped by the intervention of friends and colleagues. And the film may end with all the lose ends tied up into fancy bows, but its heart is pure.

Director Brett Haley (“All the Bright Places,” “Hearts Beat Loud”) thankfully lets the scenes breath, with quiet poignancy. Some moments are so still you can hear a leather jacket stretch. The script also doesn’t insult the audience by adding unnecessary descriptive lines.

It helps when you have an actress like Cravalho, who allows us to see pools of sadness, yearning and hunger behind her eyes. The “Moana” singer also gets to belt out a moving tune. You couldn’t ask for more from her in her first leading role in a live action movie: She’s awesome. She’s spectacular.
