Once a purveyor of polished, classy star vehicles – having directed Gong Li is Breaking the Silence and Zhou Yu’s Train, and Li Bingbing in I Do –  Zhou Sun seems to have devolved into a tone-deaf hack, on the evidence of the dire 2015 sci-fi comedy Impossible, and The Human Comedy, a criminally unfunny caper. It follows Allen Ai as a debt-ridden radio presenter who, much to the chagrin of his wife (Wang Zhi), becomes embroiled in a spoilt kid’s (Lu Nuo) ill thought-out scheme to repay his debt to a gangster (Simon Yam) by faking his own kidnapping and getting his rich father (Jin Shi Jie) to pay a ransom. The hitch is that said father isn’t too keen on getting back his son, whom he considers a massive failure. Speaking of massive failures, The Human Comedy is visually drab (lifeless, grey-ish cinematography and listless handheld camerawork reek of laziness), narratively muddled (the countless twists and double-crosses bore quickly), and never funny one second. Veterans Simon Yam and Jin Shi Jie are lone flickers of life, the talented Wang Zhi can do nothing with her thankless ‘resentful wife’ role, while Allen Ai and Lu Nuo gesticulate annoyingly – and with no chemistry whatsoever. This is an artistic nadir for Zhou Sun; let’s hope the only way for him is up. *
