Most critics agree on two things: Mark Ruffalo’s dual performance as the twins is the reason to watch, and the series is relentlessly grim. Nearly every review calls the acting exceptional, several singling out how completely Ruffalo separates the two brothers, and the supporting cast is praised alongside him. Derek Cianfrance’s direction is generally judged handsome and controlled, with the adaptation of Wally Lamb’s novel described as sensitive and serious.
The split is over whether six hours of suffering is earned. The warmer reviews find grace in the way the series handles trauma and call it devastating but rewarding. The cooler ones describe compassion fatigue, a lack of narrative tension and little wider insight. The Independent admires the writing and acting but finds it impossible to recommend, and The i Paper calls it a waste of an excellent cast. The spread is wide, from enthusiastic to outright dismissal, with the middle ground conceding the craft while questioning the point.
