“You People” is a film about race, culture, and love, and it most certainly wants to be a comedy up until the moment it suddenly decides not to be one anymore. The screenplay is credited to Kenya Barris (who also directs) and Jonah Hill, but there’s no evidence in the movie that anything was actually written down. Instead, the picture plays like a long improvisational challenge between actors eager to engage and actors who no longer have much interest in onscreen performance, with the endeavor fighting to achieve some type of shape as it blindly jumps from one scenario to another. “You People” hopes to update the premise of “Guess Who’s Coming to Dinner,” but Barris and Hill aren’t ready to think things through with the feature, which offers only limp riffing and dismal formula, assuming some type of importance when it can barely summon up the energy to create a genuine set-up and punchline.
