There’s no obvious explanation why farmer Old Wang’s swine herd starts to die off. Then again, equally unlikely are the plights of assorted other folk we meet in this buoyant, wide-ranging satire on modern Chinese capitalism: the American expat architect hired by a shady real estate conglomerate; Wang’s estranged sister (Vivian Wu) resisting family home eviction by said corporation; or his son (Mason Lee), posing as a successful businessman when he’s really eking out a living as a waiter. Feature debutant Yan’s gradual interweaving of these tales is performed with an old hand’s casual elegance, while the sheer vitality of her tradition-versus-progress debate evidences a neophyte’s go-for-broke invention. And the singalong finale will make you squeal with delight.
