Brittany Runs a Marathon ★★★½

BRITTANY has a great heart and hits its comic and inspirational moments with aplomb. While the film's supporting characters often feel uni-dimensional and a few of its thematic ambitions feel undeveloped, these elements matter less for the total effect of the movie. Plus, Jillian Bell's lead performance is impressive, from the superficial elements of the way she looks to the foundational elements of the way she builds Brittany's emotional life, both her biting snark and bleeding sincerity.
