From NetFlix:

In this David Cronenberg-helmed biopic, Viggo Mortensen stars as Sigmund Freud, whose relationship with fellow psychology luminary Carl Jung (Michael Fassbender) is tested when Sabina Spielrein (Keira Knightley), one of the first female psychoanalysts, enters their lives. This World War I-set drama also stars Vincent Cassel as Otto Gross, a disciple of Freud, and Sarah Gadon, who plays Jung’s psychoanalyst wife.

Although the story is interesting (and let’s hope somewhat historically accurate), the dialog is at times rather stiff. At a few points in the film I was a bit bored (but that is very subjective).

Keira Knightley as Sabina Spielrein starts out exaggeratedly hysterical only to suddenly appear as a cured patient about to become a famous psychoanalyst. Whatever happened to believable transitions?

You will hear quite a bit of academic psychological discussion that at times seems almost didactic.

Do you suppose Carl Jung actually engaged in S&M sexual practices with his patients?

Personally I found this film to be not terrible but still somehow imperfect. Sorry.
