My take: solid production, ultimately disappointing. Aimee Carrero's Honey was excellent though, the funniest person onstage AND the most moving.
Each performer was clearly a VERY good actor but...they mostly were operating in too narrow of emotional ranges to sustain three hours onstage.
And the direction was unimaginative -- again, totally workmanlike but...very rarely surprising or arresting.
A lot of the blame IMHO is Quinto as George...I've loved him onscreen and in The Glass Menagerie on Broadway, but his George comes out the gate so angry, it's hard for him to have somewhere to go. He seems to be losing his voice which is totally understandable, and the raspier voice actually fits, but *within that* he has way not enough modulation of tone/volume/emotion (except for a few beautiful moments here and there).
Moreover, it's not that he seems "young" (though he does -- George is supposed to be 6 years younger than Martha but look older, according to the text, while these 2 performers have an 11 year age gap that feels like 16 years) -- it's that Quinto is so VIBRANT, so powerful and athletic seeming even in his haunched-George-posture. And Flockhart is definitely a stage performer but doesn't have the power you need in a Martha. So, for much of the night it feels like George is bullying Martha. Plus that makes for a weird dynamic where George towers over the athletic Nick, doesn't quite click. (Although the YOUTH of Nick & Honey is great -- their stature and youthful faces make them look like infants next to George & Martha).
And there's the ultimate sin -- I didn't buy the love between George and Martha...
ALL THAT SAID -- the script is so strong and it comes through and no one was *bad* and it's a very watchable evening.
Should disclose that I came in as a V Woolf snob -- someone who saw the Bill Irwin/Kathleen Turner production 2x, love the Nichols film, have worked on the show. Then again, my partner who had zero familiarity with the material exited thinking "the script seems really good but why was I left bored and confused about what I was watching..."
