“After ten years and a number of ambitious works (commercially successful and critically controversial) such as Carrie, Dressed to Kill and Blow Out, Sisters arguably remains Brian de Palma's most completely satisfying film. Like Dressed to Kill, it is an elaborate variation on Psycho; unlike it, its attachment to the feminine viewpoint is much less compromised. Like all de Palma's films, it invites a psychoanalytic reading (‘the wound' as symbolic castration). Few Hollywood films (and perhaps no other horror film) have explored so rigorously the oppression of women under patriarchy and its appalling consequences for both sexes.” --Robin Wood
