Johnnie To's second film of 2011 about the investment banking industry (after the romantic comedy Don’t Go Breaking My Heart
) is one of his very best, an entertainment that also offers an impassioned critique of corruption in contemporary life. Structured like a fugue, it weaves together three stories—about a low-level hood, a naive young banker, and a stoic police detective, all of whom get sucked into the speculation economy—and To moves fluidly between tragedy and comedy even as he steadily builds suspense. Despite having very little on-screen violence, this often feels like an action movie, its portrayal of the financial markets as tense and exhilarating as any of To's celebrated gunfights.
