Kids hang, get up to no good, and ask wildly inappropriate questions (“Can black people get sunburned?”; “Would you rape your parents if you had to?”; “Don’t thank me; that’s gay.”) in Jonah Hill’s promising debut as a writer-director.

Stevie (The Killing of a Sacred Deer’s Suljic) is a 13-year-old in 1990s-era LA who falls in with the older, cooler kids that he meets at a Motor Avenue skate shop.

Hill’s clever, observational dialogue flags how arbitrary teenage social standing can be. For all their chilling, the shifting group dynamics between the charismatic Ray (Na-kel Smith), the sweary Fuckshit (Olan Prenatt), and Ruben (Gio Galicia) – as filmed by Fourth Grade (Ryder McLaughlin) – crackle and seeth.

Stevie’s home life, with a frequently absent mom (Waterston) and a thuggish older brother (Hedges, nuanced even while playing a bully), is equally dramatic. Harmony Korine cameos as one of mom’s sexual partners, but you can feel the influence of Korine’s Gummo and Kids long before he appears on screen. The hazy (and sometimes hazing) summer antics of Richard Linklater’s Dazed and Confused provide another touchstone, as does Kevin Smith’s similarly profane Clerks. Director Kelly Reichardt’s regular cinematographer, Christopher Blauvelt, brings a handmade, freewheeling aesthetic.

Period details (CD Walkman, Ninja Turtles duvet) are welcome and not overused. An original score by Trent Reznor and Atticus Ross is complemented by contemporaneous sounds from Pixies, Morrissey, Souls of Mischief and Nirvana.

Drugs are taken. Heads are cracked. House parties are low-key wild. Super Nintendo controllers are used inappropriately. Often Mid90s feels like a male retort to Greta Gerwig’s Lady Bird or Crystal Moselle’s Skate Kitchen.

Suljic, like his newfound crew, is by turns boyish, cocksure, adventurous, freaked out, unsure of himself and dumb as a rock. It’s a terrific interpretation of a cleverly constructed, superior coming-of-age narrative.
