With so much American cinema of late designed to slap us back into juveniles, it's a blessed relief to have a movie remind us how it felt to be accelerating into adulthood.
Not that Moonrise Kingdom is a typical coming-of-age film - it is a Wes Anderson movie and a return to live action after his entertainingly eccentric stop-motion creature feature The Fantastic Mr Fox.
And as with some of Anderson's previous films, the combination of precocious kids playing off offbeat adults risks this being a quirky indulgence which will overstay its welcome. The director has had plenty of those among his career.
But Moonrise Kingdom turns out to be heartfelt, deadpan-hilarious, and sweetly melancholy. It's the sort of Wes Anderson film you don't have to like Wes Anderson films to like (or if you do, it's right up there with 1999's Rushmore).
Not that the director has pulled back from his distinctive, affected style. Watching this, it can feel as if you are peering into the film's late summer of 1965 world through a giant moving Viewmaster into a parallel storybook world.
