That makes Mr. Radcliffe the only reason to see the show, and contrary to what the title suggests, this young actor really, really tries. (He even does a somersault and lets himself be passed through the air for a football fantasy sequence.) His effortful performance is sure to stir maternal instincts among women of all ages (and probably some men too) and comradely protectiveness among his fans. And - who knows? - perhaps with time this game, engaged performer will come up with a real character to play here. Meanwhile, when he leads the show's big finale, the satirical rouser 'Brotherhood of Man,' you can be forgiven for thinking it might better be titled 'Brotherhood of Manikins.'
