Gun-toting hotties combat assorted villains and their robot henchmen in this tawdry, repellent action fantasy. The heroine is a nubile, saucer-eyed waif (Emily Browning) whose mother dies and whose stepfather, coveting the girl’s inheritance, sends her to a mental asylum that morphs into a brothel. Unwilling to live as a sex slave, she transforms into an an anime-style warrior princess and leads a crew of her scantily clad fellow inmates on a series of violent quests, jumping noisily from one alternative reality to another. Oscar Isaac plays the seedy caretaker/procurer with relish, but the real pimp here is writer-director Zack Snyder (300, Watchmen). With Carla Gugino, Abbie Cornish, Jena Malone, and Scott Glenn.
