Saw this interesting post by David GoldmanYou can't adapt "Don Giovanni" to the 20th century. Between 1630 when Tirso de Molina wrote "The Trickster of Seville" and the turn of the 19th century, no fewer than 1,700 published versions of the story appeared. Tirso came from a converso family, and his play is actually a Jewish joke: If you can repent and be saved at any given instant, why not continue raping and murdering for the time being and be saved later? This paradox got the undivided attention of the 18th and 19th century, and did more to undermine the Catholic Church than all the philosophers combined. By the time Byron wrote his "Don Juan" the culture had ceased to be religious and interest waned. See https://www.facebook.com/david.goldman.967/posts/1240521096055301
