The most compelling throughline in “Both Things Can Be True” takes up the least amount of screentime. In what feels like nothing I’ve seen on network TV before, Randall attends a group therapy session for transracial adoptees in which a diverse group of people speak openly and honestly about the uncomfortable truths of their lives. The way that multiple things can be true at once. That even though many of them love their adoptive families, they also carry a resentment at having grown up othered in their own homes and communities. It’s hard to let go of their “Ghost Kingdoms” the dreams of how their lives might have been if they’d grown up with their biological parents. One woman shares that she wishes she had never been adopted at all.
