Instead of Derry in the ’80s, “Summer” plops us in the Martha’s Vineyard of the mid-’90s, where young Noah (Mason Thames, previously the lead in “The Black Phone“) plans to spend his summer with his best friends, help his mom (Nora Zehetner) run her B&B, and putter around on ten-speeds through the empty streets of the quiet suburb. But his grand ambition is to be a hard-hitting journalist like his pops, who died long ago (Spielberg riffs, like Pixar movies, can only ever give a child protag one parent). Problem is, the scandals he tries to break fall on deaf ears with the skeptical editor of the town newspaper (a fascinating cameo by Kevin James, playing it totally straight with a goofy Southern drawl), who insists he wants fluffy stories to attract tourists. Shades of Amity, right down to dressing like the mayor from “Jaws.”
