Lianna
In John Sayles's intelligent, naturalistic 1983 drama, a dissatisfied wife (Linda Griffiths) has an affair with a female colleague and realizes that she's a lesbian. According to Noel Murray (A.V. Club), "Sayles indulges a few movie-of-the-week clichés as Griffiths suffers the scorn of her children and friends, but he smartly focuses on her excitement as she figures out how to be more open, and learns that a stronger sense of self won't prevent loneliness."
