Adrian Tomine's 2007 graphic novel Shortcomings is a sharp, insightful, and dryly funny story with a protagonist who could easily be described as insensitive, self-centered, and condescending. That doesn't sound like something that would lend itself to an accessible film adaptation, but Tomine and director Randall Park have made Shortcomings into an entertaining, audience-friendly movie while remaining faithful to Tomine's original story. Park's version of Shortcomings is brighter and glossier than Tomine's graphic novel, but it retains the source material's acerbic wit and commitment to unlikeable characters.
