A rapacious, property-developing mayor threatens the city park home of Surly Squirrel (Will Arnett) and friends in a story that, for a fleeting moment, feels like a rodent version of Francesco Rosi’s Hands Over the City. This soon dissolves into a frenetic, madcap caper that sees Surly enlist the help of kung fu master Mr Feng (Jackie Chan), the impossibly cute “weapon of mass destruction”. It’s a decent if unexceptional family option.
