I can't speak to the production at the Signature, but I saw an earlier incarnation of Galati's production at the Goodman where it was choreographed by Ann Reinking. (I can't recall offhand if she was still attached at Signature.) I thought the show as an overstuffed, overlong mess, struggling to figure out what it wanted to be and careening from one tone to another in moments.
I returned to see it on Broadway with some reluctance and was bowled over. I thought Doyle had made a masterpiece of it--both in terms of streamlining the writing and creating a haunting, sparse, visual landscape that matched the darkness at the heart of the story.
