Warner Bros. follows The Lego Movie, its hit children’s animation based on the beloved construction-block toys, with a sequel that digests the whole eight-decade history of Batman. A vast mosaic of pop culture in-jokes, the movie touches on the character’s various incarnations from the comics to TV to the apocalyptic Christopher Nolan movies (which are wickedly parodied). I was dazzled by a sequence that reunites the dozens of supervillains, some familiar and some less so, who have accumulated around Batman over the years. Unfortunately the filmmakers embrace a perpetual-motion ethic that prevents them from sticking with any idea for long, and despite all the material they’ve got with the Batman legend, they feel compelled to drag in King Kong, Godzilla, the Wicked Witch of the West, and the Justice League of America. A movie of endlessly hurtling momentum, this is Mad Max: Fury Road for five-year-olds, and not nearly as much fun as snapping those bricks together. Chris McKay directed.
