This was my first experience with the show and I enjoyed it overall but I think it has some large flaws (though most of what didn't work for me was in the show itself and not necessarily this production, especially act 1).
I like the idea of bringing it back to its roots with an all Asian cast, but I thought translating the opening song to Japanese without subtitles was a bit of a mistake, since the whole point of it is to contrast it with the opening of act 2, which doesn't work if we don't know what's being said. I thought the puppets were generally well utilized, though I liked the bunraku puppets in act 1 better than the shadow puppets in act 2 (which could sometimes feel a little clumsy, though used to great effect in Rising Up).
I agree that Zachary Noah Piser and Ann Sanders were the highlights, though I thought the whole cast overall was very strong. I think the direction in act 1 could've pulled it together a bit better (though again, I think most of my faults lie in the original writing), but act 2 was fantastic overall.
