This is a difficult submission to review. I'm gonna ignore the animation/art/voice acting, because yeah, they were good, but not the focus of the movie. This is supposed to be a parody, right? And whether you like the object of your parody or not, the purpose of this type of humor is usually to make subjectively witty observations and gain more insight regarding your target. Your staple style of chaotic animation, pacing and editing juxtaposed with extreme violence is fine here, except it doesn't really work to support the movie. What's the point? What are you saying with this parody? Even if you just want to make something funny, it still needs to have a focus and a goal.
Of course, this probably wasn't meant to be reviewed in detail and I'm taking it more seriously than I should. Oh well.
