I felt more like he was doing stand-up. Very funny stand-up, but not really acting. Someone mentioned Harvey's grating voice in Hairspray. While it wasn't beautiful to listen to, Harvey sang, danced and acted his butt off in that show. Sutton, Danny, Troy and the rest of the cast act rings around Bob Martin in my opinion. I would be pleased to see him take home the Tony for best book, as the book is very funny and clever, but I don't feel he's giving the best musical actor performance this year.
PS...Suedenymes, I hadn't thought of that angle, and actually, I agree with you.
