I was there tonight. I heard some grumblings and noticed a few walkouts too, but I have to admit I liked it. You really, really need to check your brain at the door and it's possible to have a fun time.
If they do a little trimming that will help, and it probably should just be a one act. The story is thin and there aren't really any surprises in the plot so you can't let anything drag. As Mr. De Bris advised, "Keep it happy, Keep it snappy, keep it gay."
As others have mentioned I had issues with the sound. I get it's an early preview, but some serious attention needs to be paid to the balance between the singers and the band. My second issue may be related because the sound balance could have thrown off the actors, but there were quite a few sour notes from several cast members.
The show benefits from saving the best song for the end and it's pretty hard not to walk out of the theater humming "Give It Up." The score reminded me of Altar Boyz at times, with some Legally Blonde thrown in. The lyrics aren't especially witty and I think it would lift the show if you were able to keep laughing during the songs. The book has some funny stuff in it, but the songs stop the humor. Luckily the cast has boundless energy to mostly put them over.
I enjoyed Patti Murin and think she was a winning heroine. Jason Tam was excellent as well. Liz Mikel steals her scenes and looks like she's having a good time.
I guess this is the [tos] or Bloody, Bloody of this season, but doesn't have the heart of the former or lampooning qualities of the latter. Sadly this show will have an uphill battle attracting an audience, so if you're interested see it now. It does (mostly) succeed at being good, fluffy fun.
Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
