The Tonys should never have allowed voters to vote for the three of them as a group without voters having seen all three performances. The Tonys insist that every voter has to see every nominee in a category, but then they made an enormous exception here.
I personally saw one of the three, and while he was a great dancer and a competent actor, Tony winners should not be just competent. No knock against the actor, who did not create the system, and who gave a satisfying performance, but it was by far the worst Tony-winning acting I have personally ever seen.
At least they learned something by the time Matilda came around. I don't think the Tonys would allow actors in the same role to be lumped into one nomination again.
