Owen Gleiberman Chief Film Critic How distraught is Annette, the severely troubled British mother of two played by Daisy Ridley in “Magpie?” She has gotten a short angular haircut, one that might, in another context, be the height of chic (very Isabella Rossellini). Except that the movie uses it as a symbolic expression of her trauma, like Mia Farrow’s iconic Vidal Sassoon cut in “Rosemary’s Baby.” Annette, who’s on some serious medication, looks at a mirror until it breaks. Does she have telekinetic powers? No, she broke it with her hand (which bleeds into the sink), but the force of her repressed rage is palpable.
