Those two words are all you need to know. This movie is long on action, and short on plot. That's not to say there isn't a plot, but it's very predictable, and just barely cohesive enough to hold together the almost random scenes of gratuitous violence (Actually, violence isn't a good enough word. It's more like extreme slapstick) together. However, there is a method to the madness. This is FAR more than a bunch of swordfights with arterial spray thrown in. The methods of death-dealing are what makes this movie an unexpected gem. Anyone can cut off a sushi chef's fingers, but what movie has the testicular fortitude to make him eat them afterwards? If that's what you're into, then this movie won't sit on your shelf much. Every one of your equally sick friends will be wanting to borrow it, and that's a fact!
Ami Hyuga sets out to find her brother's killers, but she loses her arm in a foolish attack against them. After a narrow escape, she is aided by another victim's family, who helps her to build a powerful weapon in order to destroy the Kimura clan once and for all! MACHINE GIRL blasts its way into the next generation of Tokyo shock cinema alongside its ultra-violent cousins like MEATBALL MACHINE, ROBOGEISHA, and TOKYO GORE POLICE. Splatter specialist Yoshihiro Nishimura puts on another vulgar display of missing limbs, exploding heads, and other absurd gags that use everything from chainsaws to drill bras. The film's bloody revenge plot shares much more in common with the Japanese grindhouse classics like LONE WOLF AND CUB or LADY SNOWBLOOD rather than the more recent gorefests, although they each contain plenty of high-powered action sequences and geysers of blood. The acting and storyline here are also taken slightly more seriously than the other films of its kind despite its lighter tone. MACHINE GIRL's endless brutality and off-the-wall humor make it a must-see for hardcore gore fans!
Watch the preview, which should be on this page, and you'll have an idea of what you're getting into. If you're good with that, then you'll enjoy the rest of this movie.
Basically, Bullies kill her bother so she goes to seek revenge and gets pulled deeper into conflict as revenge against the killers of her brother brings revenge against HER from the relatives of the people SHE kills, orchestrated by the local gang leader!
There's plenty of action but it's not a "serious action drama", as evidenced by the preview: all wounds produce about 10 gallons of blood, usually in a spray all around the room. So it's kinda campy, but fun. It's basically a Japanese "Kill Bill".
Honestly, though, I think I would have preferred an option for English subtitles rather than the dub. I deduct one star mainly because the quality of the English voice acting could have been better.
