From TalkinBroadway:
"As played by Molly Ranson, Carrie is now a spiritual nonentity, neither a woman about to break free of her girlish confines or a monster in demure clothing. She comes across as little more than an empty receptacle for schoolmates' taunts in one half of the plot and her mother's dominance in the other. Ranson does little to explain who she is, and hints at none of the playfulness, sauciness, and rage that events demand from the character. Her only adequate singing voice, and an unfortunate tendency to clench her eyes shut while singing, make it even more difficult to relate or sympathize with her.
Marin Mazzie, on the other hand, has consciously chosen to portray Margaret as an Everywoman. That's fine in theory, but it has major deficits in execution, as it does not give Margaret the psychological underpinnings she needs for her increasingly appalling actions over the course of the show. Deploying a careful mix that avoids either full soprano or full belting and thus fails to convey a committed personality, Mazzie's Margaret seems so milquetoast in demeanor and even reasonable in her demands that her behavior cannot stun or outrage, and her songs cannot impress."
Yup.
"I am the sound of distant thunder, the color of flame."
