Don Hall and Chris Williams’ animated adventure Big Hero 6 (B-) is a triumph of style over substance, with an amazing hybrid metropolis imagined as a cross between San Francisco and Tokyo and a Marvel comic inspired origin story about a sextet of superheroes. There’s an Iron Giant-style central relationship between boy and gentle robot that provides much of the film’s comic and emotional heft, and there’s a sinister scientific subplot that propels the rise of a super villain. The characters are out of central casting, and there’s no breakout voice talent, prompting the most joyous parts to be the chase sequences through the cool cityscapes. The story is rather routine, down to the training montages and climactic showdown. Really, this is all about the action and the visual spectacle, and those elements are grandiose. It’s startlingly original for a Disney film but not that trailblazing otherwise.
