The only other noteworthy aspect of this movie is how the filmmakers chose the "fuck your vision" technique when it came to special effects. They literally smear the screen with what's supposed to be blood during every fight scene, so you can't make out jack shit. For the climactic battle, they add blood smears, blood flying things, and piss-poor lighting. I imagine it'd be like watching a kung fu fight if you were being repeatedly kicked in the head and trying to see through a dirty window at the same time.
Conclusion: I feel bad for actual Japanese schoolgirls -- they must be living in a constant state of terror. From what I can understand of these films, schoolgirls have a lot to do with cleavage and butts in Japan. But if I'm being fair, there's a fairly creepy North American sexualization of schoolgirl uniforms as well -- it's just not as mainstream as this. We didn't make a popular cartoon about it or anything.
None of these movies take place at school. In fact, only one even had scenes in a school. Do schoolgirls in Japan just not have other clothes? Also, it's been established in the last movie that the world ended 20 years ago, so that girl never even started school. Why does she have an outfit that is her size when she's in her 20's and one of only a handful of humans left alive? No, this doesn't make sense at all.
I'd been hoping to see if I could determine a link between schoolgirls and horror, or an understanding of where schoolgirls fit into the pop culture of Japan. I could half-ass a thesis on innocence and the interplay between it, hardcore violence and death, sexuality, and adulthood. But I don't think that pans out in any of the plots when you consider all the murdering and jiggling I just watched. I think it's boners. I think schoolgirls are used for boners in Japanese cinema. They're like one more piece in an international cinematic puzzle, one that can be mostly filled in with pieces from Michael Bay movies. If we ever fully solve the puzzle, we'll have created a movie so perfect that no 15-year-old boy on earth will be able to resist it. They tried with Sucker Punch, but didn't quite make it. But one day ... one day.
