I saw this last Saturday and found it to be very enjoyable, though also clunky and far from perfect - with some weird casting/directing choices that were very distracting.
***Spoiler Alert***
I'll start off by saying that Lea Salonga is a golden voiced angel and a gift from the cosmos. WOWZA, we're so lucky to have her and I wish she was given more leading roles, and more chances to shine here in the states. Telly is a hunk of a beautiful man and also a great singer/actor. Takei was hilarious and I didn't have a problem at all with the "hokey material" he was given because it was the only levity in the show which was pretty dark overall.
One giant elephant on stage that really bothered me to the point of distraction was that there were only two Asian ensemble men without speaking roles who were supposed to represent the entire male population of the internment camp, while there were three white ensemble men who did nothing the entire show except sing a swing song at the very end. They easily could have cast one white ensemble member to play the role of the politician AND the guard, and hired two more actors of color to make the internment camp more believable. The entire show I just kept getting reminded that Broadway wouldn't even hire Asian actors for an Asian show - it was rather insulting, and I'm not even Asian.
Direction was also pretty clunky. It was a lot of "move to your spot in the light and stand, then cross to that spot and stand." I agree with wizzer on this one - Arima is out of chances. The really awkward death scenes need to be figured out too. Maybe they'll figure these out during previews, but the night I saw it, cast members stand up on stage in a 'special' after they die and just walk off stage awkwardly. It really doesn't work, and was rather confusing because it was hard to tell who was alive still and who had died.
The music was enjoyable and really soared at a lot of spots, especially when Ms. Salonga was singing - but don't ask me to hum a single tune for you because I don't remember a single song, melody, or lyric. The lyrics are the weakest link right now. Any complaints about the characters not having depth can be blamed on the lyrics seeming to come out of nowhere, and offer no insight to the character's minds. The book was the strongest part of the show in my opinion. Marc Acito's dark and regretful libretto is what makes the evening enjoyable. I was truly invested in finding out what happens to these characters that caused them to never speak to each other again. There were lots of people around me crying, though I didn't shed a tear personally. I was still moved by the story, which is why I inevitably had a good evening of theatre. I'm not sure what they could change between now and opening to improve the show to the next level unless they rewrote half the lyrics in the next week or so, and changed some of the clunky direction. Actually... yeah they should do that.
The strongest song in the show was the protest song that Michael Lee's character (Frankie) sings. This is the song they should take on talk shows to give people an idea of the show. It's lively, and funny, and poignant. The rest of the show needs to come up to match this song.
If the creative team is actually set on making changes as they claim, then they should get to work on improving the lyrics over the course of the next week. It's do or die time. They can sleep when the show opens and (hopefully with changes) doesn't get annihilated by the press. I have a feeling this show will get mixed reviews, with some positives in there, but the Times will probably be merciless. On a side note, I was not asked to fill out a survey, and I wonder if anyone is actually reading those surveys...
I definitely recommend seeing this for the story and for the outstanding cast that are giving it their all. I might actually go back again after it opens.
