That guilelessness is the root of Pacific Rim’s charm: the Jaegers romp around like enormous, weaponised four-year-olds, and there is a wonderful moment in a battle off the coast of Alaska where one picks up a fishing boat in the path of a monster and tenderly sets it aside, like a rubber duck in the bath. Whatever our ages, del Toro’s miraculous entertainment boosts us all up to its gleeful point of view, where cities become adventure playgrounds and oceans pools to paddle in. Giant robots, it turns out, can be great levellers.
