Let me preface this with I am a lover of what I call historical musicals.....POTO, Le Miz, The Last Ship and more recently Zhivago (yes, I was one of two that enjoyed it).
I learned several lessons from Amazing Grace, John Newton was an evil man, this was not trivialized. I didn't know a thing about the British slave trade. I learned about some of it in this show. The score fit the theme very well and people were walking out of the theater humming.
The costumes were spectacular. I hope at Tony time if this does not survive the costumes are not forgotten.
As I said, sitting in house left, row C, seat 1 several things happened......Josh sang right into my eyes. I swooned. This happened several times. ***SPOILER*** I was soaking wet at the end of act 1 and the actual end of it was magnificent. Still trying to figure out how it was done.
Sure, there were a couple of draggy moments, but the 2 1/2 hours were fine for the overall impact of the story. I cried several times, yes, I'm a sap for this stuff. And the entire filled theater got up on their feet before the curtain went down, after the beautiful chorus rendition of the title's song.
