I saw it last week. It's a LOT of fun. It feels like a party masquerading as a play, which was obviously the director's intention as the cast mills about the audience, introducing themselves and striking up conversation before the show and during intermission. There's a bottomless punch bowl and hors d'oeuvres to be had as well.
It's one of those shows where you just put your brain on snooze and let yourself go and you'll have a ball. The soundtrack consists almost exclusively of Scissor Sisters, if that gives you an idea of the atmosphere: very gay, very colorful, very fun.
I've been recommending it to anyone who'll listen.
