I saw the production last night. I did not find the "modern" set particularly "modern" or disturbing/distracting in any way. The only item that caught my attention as anachronistic was the shiny, white, wireless telephone. Honestly, though, I noticed it only fleetingly as I was too busy being riveted by the performances.
I'm utterly perplexed by the notion that Anderson isn't bringing anything "new" to her interpretation--as though such an intense, fully-inhabited, emotionally honest and, ultimately, devastating performance is some kind of ho-hum, every day experience that requires some new "spin" or insight to make meaningful. It's all there in the text, of course, and I've been reasonably moved by less fully-realized performances, but I thought Anderson was magnificent.
Unusually in my experience, I felt that all three principals--four, if you count Mitch, as I think we should in this case--are in the same production, giving well-matched performances. Stanley is not the brutal caricature that so often comes from actors doing their best Brando impression and Stella is a (heartrendingly) real person.
I can't explain why the direction of the stage rotation changes--presumably it signals the moment at which the director feels the universe of the show "shifts gears"--but I loved the effect of the moving stage. I felt that I was being given powerful, physical (and emotional) access to the events taking place on stage--almost like the experience of stumbling upon Macbeth in the bathtub in "Sleep no More".
I am in awe of Ms. Anderson's ability to take this journey multiple nights/week for weeks on end--I can't imagine what it does to her psyche.
You think, what do you want?
