So it's to their eternal credit that Cornwall's Kneehigh Theatre have cast all memories aside to work their own kind of magic on the myth. Though staying true(ish) to the moral heart of the fable - you must rule your desires, don't let your desires rule you - director Emma Rice and her versatile company present a timeless take on the story that, cheeringly, lays the fate of the heroine's destiny firmly at her own door. And ours too, of course.
