A super sweet, affecting comedy with a magical premise and a terrific central performance from Larson herself.

Larson navigates through a cute story’s clear limitations to deliver a film that’s often quite funny, even if it sometimes flirts with being cringe-worthy.

While the film may not entirely hang together, the stakes are low, and its bright spots point toward a promising future for the behind the camera talent.

It’s a candy necklace of a movie: sweet but chalky.

Though the screenplay ... ultimately conforms quite plainly to formula and grows less interesting as it proceeds, there’s a gutsiness to Larson’s headlong leap into material that walks a fine line between risky fantasy and feel-good reassurance.
