I saw the show yesterday, so I'm just popping in to throw in my two cents. I'm in the boat with some of the others who saw it - I really enjoyed it, but I wouldn't say it's a must transfer. Steven was excellent and found a good balance between the darkness of the character and the need for redemption at the end. Charlotte took a thankless role and gave it some spark - and her dancing in the Louise ballet really worked well. Laura was strongest in the shows final scenes, but her line reading of the "Sometimes when someone hits you it does feel like a kiss" really did not work (honestly, the whole line just doesn't quite work in today's climate, but aside from cutting it, I'm not sure what you can do. Also, most of the audience laughed at Billy's "I hit her because she was right." line, which was played for the laugh- a choice that didn't sit right with me either.).
Jenn and Michael were superb and I loved their interplay. The only actor who didn't quite fit was Denyce Graves. Now, I understand that this is the Lyric, and there's a need to bridge the opera community and the musical theatre community, but Graves just didn't fit here. Having an opera singer in Show Boat, Oklahoma, and Sound of Music works. Here, she just stuck out like a sore thumb. I'll admit, I'm not familiar enough with Carousel to know if her character is normally played by someone with such a full voice, but it's jarring to hear Graves' voice after listening to the other cast members. Just my own thoughts.
Over all, it's a really excellent production. I liked Ashford's direction/choreography, the sets are interesting and minimalist, and the lighting is wonderful. The 37-piece orchestra is stunning. If they can keep the core creative and cast together for a transfer, I think it would be very well received. But if you're in Chicago, I recommend checking it out. It's a very well done production.
