I was there last night. I thought it was a really enjoyable night of theatre, and I think it will only improve over the course of its run. The play manages to balance very heavy material and very broad humor. A lesser director may not have been able to balance the different tones that the play requires. While Lupita Nyong'o's role may have the largest emotional arc, this play is very much an ensemble piece, and all five women are exceptionally talented. It felt a little long, but I'd expect they'll tighten it up over previews. I was very excited by what I saw last night!
