About
"Grief and mental illness rendered almost unbearably intimate"
A miniseries about identical twin brothers, one of whom develops schizophrenia, and the other who spends decades trying to hold their fractured family together. Mark Ruffalo plays both roles, anchoring a story that moves between past and present as buried trauma, guilt, and generational damage slowly surface. It is slow, heavy, and unrelentingly sad, built on long silences and devastating close-ups rather than plot momentum. What carries it is the acting, especially Ruffalo's dual performance, which turns grief and mental illness into something raw and specific rather than melodramatic.
Mark Ruffalo's devastating dual performance as two brothers shaped by trauma and mental illness.
you find sustained bleakness and slow, grief-heavy storytelling emotionally exhausting.
