I saw tonight's performance and, in my view, it was pretty uneven.
The weaknesses
Ronan was mediocre at best in a crucial role. Okonedo, despite some nice moments, was sometimes weirdly mannered -- overacting in, perhaps, a failed attempt to portray her character's insecurity about her supposedly plain looks. Whishaw, who I really liked in The Hour, sometimes came across as a bit too petulant and, in Act IV, far too weepy. In fact, throughout Act IV in general, more stoicism would have gone a long way -- it became quite soggy and drawn-out for my tastes. Also, in every Act (as far as I can recall), the scoring was, at times, overwrought and even hokey.
The strengths
Most of the rest of the cast was good, with Norton and Hinds especially so. In fact, I thought Hinds was just about perfect for his role as a judge who mixes genuine religious belief with pompous self-interest.
Acts I and II were solid and Act III was terrific.
Slight Spoilers
Last, in regard to a couple of other points mentioned in earlier posts: The writing on the chalk board is something like "The Promises of Dutiful Children" or words to that effect. It's a list of things the kids should do: honor god, your king, your parents, etc. And it gets obliterated as the kids rebel in their grey, prison-like classroom.
As to the floating girl -- although I think I understand possible reasons why it does not need to suggest literal witchcraft, I still think it's a bad idea. I saw the show with someone from another country who was unfamiliar with both the play and US history. Because of the seemingly supernatural scene, that perfectly intelligent person thought that, within the world of the play, somebody must really be an emissary of the devil and thus found the storytelling more confusing than it (arguably) should have been.
