Neil LaBute’s Your Friends and Neighbors (B+) assembles a perfectly nasty ensemble of characters to showcase the darkness of modern-day suburbia. Although big stars such as Ben Stiller give the film marquee value, it’s LaBute’s tart dialogue on central display. Catherine Keener and Jason Patric are among the most deliciously hateful, with the latter’ third-act soliloquy one of the film’s most memorable. Fans of dark comedy will be tickled crimson with this bloodbath of the bourgeoisie.
