I cannot recommend it enough. It is dark, scary, upsetting and absolutley watchable. We got standing room seats for 25 dollars and although not everyone may want to stand for 2 1/2 hours, for me it was worth every penny. It makes me feel better about the state of Broadway.
This show pulls no punches and despite what Isherwood says it is much more than just a story. I think it brings up a lot of worthwhile questions. But go see it. right now. go. really. go.
