I couldn't pick just one, but narrowed down to two:
Will Swenson for Actor in a Featured Role (Musical) - I've seen several productions of Hair, and always found Berger to be nothing more than an annoyance and an asshole, but for the first time, I finally cared about the relationships he has with Claude and Sheila.
Joe Turner's Come and Gone for Revival of a Play - I had never seen or read anything by August Wilson, and going into the play, I was almost preparing to leave at intermission. But it sucked me in, and even now, it stands out as the most I've enjoyed any play this season.
