The formula in this badly acted magic-less fantasy film becomes clear right from the open scene. Woman gets raped.
Woman kills at least five guys.
But it doesn't really matter who gets killed off and who doesn't. When the badguy meets his end, there's a moment where it looks like one of the women might die with him. I marveled at how little I cared one way or the other. When he finally concedes, he does it with a certain half-smile as if he were finally agreeing to let his children buy a popsicle from an ice cream truck. This movie doesn't answer any questions at all but instead relies upon the viewer's knowledge of archetypal stories to get by.
