'It's Always Sunny in Philadelphia' writers Dave and John Chernin deliver epic spectacle without testing their teenage heroes.

The sickening high school comedy: We all get older, but they stay the same. “Incoming” is the latest addition to the genre, a Netflix release written and directed by Dave and John Chernin, who cut their teeth on the historical vulgarity of “It’s Always Sunny in Philadelphia” before creating the short-lived but memorably raunchy Fox comedy “The Mick.” The filmmaking brothers’ story for “Incoming” is chock full of tried-and-true tropes: the drunken freshman, the cranky sister, the wannabe lady version, the blonde queen. But the Chernins create a jaunty pacing that energizes these familiar ingredients, more in the joke department than in the film’s superficial dramatic components.

Fourteen-year-old boys aren’t the most complicated people on the planet, and “Incoming” knows that, establishing its main ensemble with a feisty opening act that capitalizes on the Chernins’ sitcom roots. Four insecure young men have taken on the gauntlet of high school. Benj (Mason Thomas) is convinced he can date sophomore Bailey (Isabelle Ferreira). Connor (Raphael Alejandro) hasn’t hit his growth spurt yet and has been given the nickname Fetus. Eddie (Ramon Reed) hates his mother’s rich boyfriend (a memorably blasé Scott MacArthur, returning to the Chernins after “The Mick”). And Danah (Bardia Seiri) is counting on him to hook up with a senior to boost his reputation. A party at the end of the week will change their lives.

Except, of course, that won’t happen. One party is just one party. Even with timely touches like TikTok interstitials and casual LGBTQ acceptance, “Incoming” is haunted by the same teenage nostalgia as many of its less politically correct genre forebears. Regardless of clique, there’s a uniform warmth to students across the high school sociological food chain. Even when someone twists their morals—as Danah does when he sets up security cameras to target his dream girl and locks her in a room with him—they’re given a quick, nut-punch comeuppance and, not long after, unconditional forgiveness.
