Much Ado about Nothing proves that Shakespeare was aware of and capable of creating a relationship of equals.
Benedict and Beatrice are so well-matched in terms of intelligence, wit, and independence that various retellings of the tale, from Branagh's magnificent and lush masterpiece to Shakespeare Retold's lovely modernization with Sarah Parish and Damian Lewis, do not need to "fix" the relationship to make it modern. Beatrice and Benedict are entirely comprehensible to us.
Hero and Claude are less likable--of which truth I think Shakespeare is well-aware. If Claude's behavior--shaming her at her wedding--wasn't so reprehensible, Beatrice would have no reason to demand that Benedict challenge Claude. He would have no reason to take her part.
The problem isn't the anger and jealousy that Claude feels. Shakespeare, as always, is dealing with entirely recognizable human emotions. The problem is, Why would Hero take him back?Shakespeare Retold leaves the matter open. And even the play veers away from the youthful idiots to the couple that draws us in.
One of the best couples in all literature!
