Democracy, last year at the Brooks Atkinson theatre. It was the best two hours I have ever had on broadway and to me no play could ever top it. I was so disheartened when it closed and Micheal Fryan's was script a touch of class.
The Pillowman was excellent but I Am My Own Wife is still at the top of my list of the hundreds of plays I've seen. The material, and Jefferson Mays, were equally fabulous.
It wasn't a broadway play, but this past may, there was an incredible 2 person production of "Turn of the Screw" at the Acorn on 42nd Street Both of the actors are bound to be very successful. Some of the best acting work & production values I've ever seen on or off Broadway
