Screenwriter Justin Lader's feature film debut is nothing short of stunning and hopefully signals a prolific career ahead. Meanwhile, director Charlie McDowell's first feature effort similarly allows for such a unique exploration of the trials of romance.

The film owes everything to its actors and particularly to Moss, who is capable of constantly surprising reactions, like the flurry of little nods Sophie gives to express delight.

Ethan and Sophie are never more than playthings of the premise; Moss and Duplass are the sole sources of nuance and vitality, and they seem unduly hemmed in by the movie's unimaginative confines.

A fever dream of marital discontent, Charlie McDowell’s The One I Love tackles a failing marriage with sci-fi panache.
