I quite enjoyed this production. But I did read this thread (when it was only 1 page long), which was good for calibrating expectations that it was a small, minimalist off-Broadway affair with bare stage and essentially no costume. I also didn't pay a ton of money -- I won the lottery -- which was a great way to see this show on the cheap. I recommend that if you are on the fence and can leave it to chance to try your hand at the lottery.
I have no previous exposure to Pacific Overtures, didn't know what it was about, and wouldn't have known about the cuts if you hadn't told me. I realized that between this and Sunday in the Park with George, I'm not a huge fan of Sondheim (hoping to give it one more shot with Sweeney Todd). Nonetheless I found this story and the characters compelling.
The story was really easy to follow. I actually liked how the actress playing Tamate drifted in and out of being an audience surrogate and an actual character within the show. When the story began to re-focus on Kayama, I think that is where it started to shine. It's odd there's confusion about Tamate's suicide, but I suppose that some people may never have heard of the practice of seppuku / harakiri (not sure which is the more appropriate term). In order to preserve your honor and the honor of your family, rather than face failure (e.g. capture by enemy), you must commit suicide (code of samurai). I thought that was pretty clear when he said, "You know what you must do" (paraphrasing). That's why when she sings, "I Will prepare for your return" (paraphrasing) over and over in an upbeat way, it was pretty heartbreaking because they were 100% confident he was going to fail.
Also, this is the first time I've seen an on/off-Broadway production with 100% Asian cast, and their performances were absolutely splendid. As an Asian-American it's always a bizarre and refreshing experience (outside of The King & I -- while I loved, I found to be almost offensive stereotyping, as it was from a white person's vantage point -- Allegiance was the first time I saw a show predominantly Asian cast, Vietgone was the other).
I really enjoyed the history lesson, too, even though it barely scratched the surface. I've honestly never though about the end of Japanese isolation and the impact of it, and this show has certainly piqued my interest.
