I, too, logged-in after a long time to echo bwaybaby12's post. I saw the production last week and think that their reaction and analysis is spot on. I had never seen a production before, though I've listened to the OCR many times over the year. I didn't always understand the context of most of the songs so it was wonderful to finally understand how the show works.
The bare/conceptual set did not bother me at all. In fact, it was quite intriguing to me that Jeremy Jordan had to stay there, on stage, not moving for the entire show. He was STUCK. (as a performer myself, I was initially worried he'd be without water for the whole show as well, but Floyd is eventually given a bottle so he was able drink) In other productions, is the actor able to be off-stage during the "up-top" scenes? When he finally got to stand in Riddle Song, it felt like such a relief and release that I started to tear-up.
I loved the staging of The Call. The stage is completely dark except for a spotlight on Floyd as he climbs up and slides down platforms that arise, unseen, from the stage floor. We, the audience, can't see more than a few feet in front of him, in that big black expanse, just like how it would feel down in a cave! (at the performance I went to, Jordan actually stopped in the middle of his climb because there must have been a technical issue. The show was paused for a few minutes and then they re-started from the middle of the song. No one else has mentioned this, so I'm assuming they have fixed the issue. Gotta love live theatre!)
I was initially disappointed in Jordan's singing, though he got much stronger throughout the show and his How Glory Goes was, well glorious. I was also impressed with how his speaking voice got weaker and hoarse towards the end, like someone who had been screaming in a cave for weeks would.
Jason Gotay was fine. Taylor Trensch was fantastic (Tony nom. for supporting?). Marc Kudisch and Sean Allan Krill were wonderful in mostly thankless parts, as always. Jessica Molasky seemed weak vocally. Perhaps she was sick? The only disappointing casting was Lizzy McAlpine. There wasn't much there acting or singing-wise and I truly don't understand how she got this job.
There have been a lot of negative reactions here, but that's clearly not the universal audience experience, so I hope that you will still check it out, if you are interested.
