Little Men is a critical yet empathetic look at the dangers of gentrification. Ira Sachs, director of Love Is Strange and the Sundance Grand Jury Prize WinnerForty Shades of Blue, accentuates the natural vibrancy of Brooklyn and brings out the best in his actors. Taplitz and Barbieri have a natural rapport and earnestness that belies their young age. Kinnear and Garcia bring weight to their roles as the feuding parents, and Jennifer Ehle, Talia Balsam, and Alfred Molina round out the cast with wonderful supporting turns. It's a triumphant return to the Festival for Sachs, who has made a film that never lets its abundant kindness interfere with its honest portrayal of a rapidly changing neighborhood.
