According to the director, Alice Haig didn't know the movie was a softcore thriller, as a result she was uncomfortable filming the sex scenes.
The movie ends without any real resolution for all the other women manipulated into killing their husbands. But realistically, the charges can be reduced to manslaughter at minimum; given the psycho who manipulated them is dead and the brainwashing machine broken.
Jane notably starts dressing less conservatively and having a happier mood once Dr Bradshaw puts her under hypnosis. If the one scene with Bradshaw molesting Jane are what happen ever session, this makes sense; Jane's subconscious thinks Don has been sexually satisfying her and she wants to entice him to continue.
Bradshaw is notably annoyed when she hears her patients say their relationships are good, just arguments like normal. Explaining why she keeps turning up the intensity of her device; so she can make them ignore this fact and find the tiniest thing about men that angers them. Then amplify it into irrational hatred.
