“I want to talk about Heidi Armbruster. She plays Chris’ barely-holding-on mother, who is trying to get back into his life. Armbruster has been a mainstay on and off Broadway for years, but rarely gets roles equal to her considerable talents. Here she is equal parts tragic and scary. Obviously the larger social significance of the character – reflecting a broader epidemic across this country – is not lost on us. But in Armbruster’s hands, she is one, not one of many.”
