Brantley certainly does have something to say...he is reacting against Broadway's technical superiority complex. I.E. The highest belting, the longest notes, the most riffs, etc etc etc.
Brantly believes there are a never-ending line of people who can belt high, do a thousand turns, kick their legs behind their ears, and sing above high C. And, he is right.
What there are NOT a lot of are people who can't be replaced. People who OWN a role with their own uniqueness, and not their ability to be technically good.
In fact, a star's quality is not their ability to be technically good, or even artistically good, but their ability to be human.
And on that note, I believe Brantley is right -- we need less technical superiority, and more humanity.
