Sorry to be the lone dissenter here - I saw it two weeks ago, and while the cast is indeed superlative they are the only reason to see it. The script is rather lightweight - it brings up some very deep, emotional issues and then skirts around them for an hour and a half. It is all very reminiscent of WHO'S AFRAID OF VIRGINIA WOOLF, without that work's depth or insight.
But it is only 90 minutes. And as I said, the performances were all stunning, especially Janet McTeer.
Cheyenne Jackson tickled me. AFTER ordering SoMMS a drink but NOT tickling him, and hanging out with Girly in his dressing room (where he DIDN'T tickle her) but BEFORE we got married. To others. And then he tweeted Boobs. He also tweeted he's good friends with some chick on "The Voice" who just happens to be good friends with Tink's ex. And I'm still married. Oh, and this just in: "Pettiness, spite, malice ....Such ugly emotions... So sad." - After Eight, talking about MEEEEEEEE!!! I'm so honored! :-)
