Undine: Christian Petzold’s film blurs the line between a romance and a low-key fantasy, or fairy tale; to his credit, he does very little to clear that, keeping the film less obvious and literal. The main problem is the title character’s nature, real or perceived, makes her somewhat cold, distant. Paula Beer gives an interesting performance as the protagonist; there is some underlying sadness and vulnerability to her tough and confident veneer. In any case, it’s not hard to see why the character played well by Franz Rogowski would fall in love with her. The film is elegantly shot by cinematographer Hans Fromm, but the work of editor Bettina Böhler cannot hide that the film has a very slight story, which can make it seem very slow-moving at times.
