The premise of the movie is quite good, unfortunately it descended into on-the-nose analysis by the annoying psychiatrist in the film, they should have gotten rid of him immediately. There seems to be a certain trend in 40s movies to speak out (highly inaccurate) descriptions of "psychological disturbances" and "Freudian analysis". Other examples like the egregious "Snake Pit" come to mind.
Maybe in future years people will scratch their head, when they hear the pseudo-scientific nonsense babble in sci-fi/superhero movies of today. And I hope that this day will come soon.
I think films were still trying to tiptoe their way in new cinematic narrative forms with a mass appeal and this is the biggest credit I can give to this film: Ealing, not a small studio being sort of experimental. Times are still/only more than a decade away before the emerging of La Jetee.
