With the method that Freud pioneered, Jung treats Sabina Spielrein (Keira Knightley), a very disturbed Russian patient who dreams of becoming a doctor herself. Once Jung cures Sabina, they become lovers. Years later, already become a psychologist, Spielrein sides with Freud, who by that point has ended his personal relationship with Carl Jung.
This movie is well acted by all three leading characters, being food for the mind since the audience is treated with dissertations on psychology’s most important theories of the era.
There are scenes of physical punishment during sex, but aside from that, the film lacks action which makes it feel extremely slow despite running for only 99 minutes. Besides, the discussions between the characters feel more like a lecture on psychology.
