The rush of narrative developments sacrifices a deeper articulation of key relationships, like Thompson's friendship with Redgrave, or her courtship with Hopkins, which seems far too hasty. But Thompson, in her signature role, holds the movie together, earnestly working to reconcile people and worlds in conflict, even as her actions threaten to drag her under. The payoff comes thanks to her heroic presence at the film's center and the patient unfolding that leads to a devastating conclusion.
