Dallas Morning News:
Another example of animation that shows just how deep something as seemingly superficial as a cartoon can get.
New York Times:
Is much more effective at evoking a paranoid mood than at telling a coherent story, and the jerky action sequences are among the film's weaker visual elements.
With its dour insularity and clingy fidelity to realism, this overhyped slashfest fails to rise above the extravagant pointlessness that plagues inferior anime.
