If it is a little too on-the-nose, then I suspect that is because we have not yet outgrown the concerns that plague this work. It's still as vivid and as extraordinary as the first time I read it, though it does reek of a little theatricality.
But beyond all else it is eminently readable, both as script and as theatre, and I do still think of it as highly communicative of its intent. Hence, the five stars.
