‘Run Amok’ Review: A Drama About a School Shooting, and Therapizing It Through a Musical, Is Notable for the Performance of Alyssa Marvin

There are a number of scenes in which "Run Amok," the first feature written and directed by NB Mager (she based it on her 2023 Oscar-qualifying short), plays like the world’s most pious episode of "Glee" (at one point we see the kids rehearse school-shooting dance numbers set to the tune of Britney Spears’ "…Baby One More Time" and Roberta Flack’s "Killing Me Softly"). At others, the film is completely low-key and dramatic in the doleful coming-of-age-movie tradition of "Eighth Grade."
