Ever since the trailer first appeared online, fans of gratuitous ultraviolence have been waiting for The Machine Girl (Cine Asia, £14.99) with as much excitement as Ted Bundy clutching a co-ed’s roomkey. “A schoolgirl with a machine gun for an arm blasting yakuza arse? Awesome!” And it truly is. When Ami’s little brother and his best friend are killed by bullies she goes out wreaking fearsome vengeance, in the process getting her arm hacked off by a yakuza family whose son turns out to have been the chief bully (incidentally, while the whole family like to get together for a bit of maiming and murder, it’s mother who is the real artiste, beating maids to death and making the family chef eat his own fingers as sushi).
