I think this is probably the best of Joan's 50s period, actually. She's very good here as the meek, scared, but resilient Millie. Despite the age gap between her and Cliff Robertson, because it's a plot point, it actually works. The direction, however, is a bit over the top and the noir-ish tone unnecessary. Also, whilst the portrayal of the descent into mental illness is accurate, the motivation seems a bit unlikely- especially for 1950s men who were a damn sight tougher than today's crop! In addition to this, the idea that someone could be get, suffer, and be cured of a serious mental illness (one supposes a bipolar breakdown) in the space of a year, obviously rather dates things- I suppose that came from the 'it's an illness like any other' period of medicine- as evidenced by the idea the electro-shock therapy could work or help 'turn people normal' when we know in all likelihood he would have come out a placid, drooling mess. Anyway, despite all this it's a good film where you care about the characters and Crawford really gives it her all.
