Hedwig is the kind of experience which is enjoyed in an intimate setting. You should be kind of close to the stage, and Hedwig, to really get full impact. Hedwig is delivering his lines as if he's speaking to you in a casual setting. Not in a large broadway house where people in the mezz and balcony may very well feel totally separated from the event.
And yes, the above remarks are my opinion, but I'm in the position to base them on the experience I had with the show.
That being said (I hate that phrase, lol) I wish the show all the success is has always enjoyed and hope it does work out on broadway somehow. It has been more than just a show for me.
