One of the reasons [William] Shakespeare is so endlessly fascinating is that you can look at that figure from about 10 different angles: Caliban in Shakespeare's day was probably viewed as a sort of comic, barbarian type, but into the 19th century there were productions where Caliban was the hero. He's a potential rapist of a minor. Is that a good thing? No, it is not. On the other hand, Prospero's got him cooped up in a cave and tortures him if he doesn't do what Prospero wants. Is that a good thing? No. Shakespeare doesn't let you off easy.
