I saw the matinee yesterday and Bre Jackson was absolutely stunning. Her Celie is in the Erivo/John Doyle mold, but she adds her own touches throughout, it's absolutely not a copycat performance. I was so impressed by her, more than I could have imagined.
Also, it may be surprising, but Jennifer Holliday became my favorite of the three Shugs in this revival! I fell in love with her interpretation of Shug. She was quirky, mysterious, but most of all she played it with so much warmth, more than Hudson or Headley. It was such a genuine performance, and I have such a new appreciation for Holliday and her great talent. If you haven't seen Holliday's Shug yet, make time to see her!
