Little is a funny, surprisingly heartfelt film, embedded in traditional themes and amplified by the talented Martin, who reminds us that she and other youth like her aren’t just adorable — they’ve got boss mentalities that cannot and should not be ignored.

What really works about Little easily surpasses what doesn’t.

Consistently funny if all-around a bit too familiar.

Little moves quickly and can feel a little scattered, with subplots about Jordan befriending a group of middle-school misfits, April’s idea for a new app, and multiple love interests. But the film is grounded by its actors, the key to any body-swapping material.

As an unapologetic genre exercise, it's also fairly harmless, painless stuff. Thanks largely to the work of its cast, which does more with Tracy Oliver and director Tina Gordon's decidedly uneven, underdeveloped script than anybody has a right to hope for, Little ends up being mostly enjoyable in its own lightweight, empty-calorie and entirely unexpected way.
