I saw HEDWIG three times (Rannells, Hall, and JCM). I stopped after that because no performance of that role could stop what JCM did. It will forever be one of my top 3 favorite theatre experiences ever.
I saw IF/THEN six times-- once in DC, one in previews on Broadway, and another 4 times including closing night. Every time I saw it, I noticed another detail, another part of the plot that clicked, or another nuance in a performance. I recognize the flaws of the show, but I loved that I could have a new experience each time.
