This story sounds a lot less ice-cold on paper. What is the heart of the show? Is it trusting in conscience? Is it finding out who the other is? When the show gets settled, it contains an intriguing game of cat and mouse, of push and pull through double-crossing, and you don’t really know who to hatch your wagon to. Imogen (Elisabeth Moss) is polarizing and dodgy, Adilah (Yumna Marwan) has a warm manner of speech, and together their arresting dynamic creates a steady heartbeat. But for a miniseries, it sure takes its sweet time getting there, if it ever does.
