Whenever possible, use strong subjects and active constructions, rather than weak verbal nouns or abstractions and weak passive or linking verbs: instead of "Petruchio's denial of Kate of her basic necessities would seem cruel and harsh...," try "By denying Kate the basic necessities of life, Petruchio appears cruel and harsh--but he says that he is just putting on an act." Don't forget that words and even phrases can serve as strong sentence subjects: "Petruchio's 'I'll buckler thee against a million' injects an unexpectedly chivalric note, especially since it follows hard on the heels of his seemingly un-gentlemanly behavior." And remember--use regular quotation marks unless you're quoting material that contains a quotation itself.
One reason for the overwhelming popularity of the play throughout the ages is that it focuses on two people who defied society in order to follow their own hearts. Shakespeare scholar Walter Cohen cites the popularity of Othello during times of great rebellion and upheaval; the play was most popular during the European wars of the mid-19th century, the fall of Czarist Russia, and also during World War II in America. These productions tended to emphasize the nobility and love of Othello and Desdemona, and made their fall seem more tragic and ill-deserved.
