Excellent period production values and execution. If you're expecting another Cronenberg "body horror" or "psychological horror" story, you won't find that in this film. The story isn't a simple one. He takes some liberties with their biographies but I don't believe any of them are that severe. There was considerable controversy regarding Jung and Spielrein, and the extent of their affair. Acting performances are excellent. The run time forces glossing through some of the details about Jung, Freud and Speilrein, and their work, while highlighting the major events. It's more about the relationships between the three than psychoanalysis itself, which would require an entire film series to cover.
