Well in this case that doesn't apply as it's fiction. But generally, not really, as if they decide they don't want to study a play, they can. You can't very well insist they provide a good reason for doing so to your satisfaction, as then you're in a glass house so to speak. And people decide to not study many of his plays for whatever reason - we skipped Tempest, Titus, Midsummer, I'm sure other schools skipped the ones we did. This sort of situation is still far from the hill to die on.
