Despite the one-of-a-kind title, TEENAGE HOOKER BECOMES A KILLING MACHINE is one of the worst ever films I've watched. It's by far the worst South Korean movie I've sat through, and this is a country normally noted for the calibre of its productions. It's amateur hour throughout, a pointless, senseless waste of time for all involved, not least the viewer.
Although the running time is only an hour long (and ten minutes of this is padded out with endless credits, half of which feel made up), this is a movie which drags on and on and on. A teenage hooker is killed by a client, then her body is turned into an android by a trio of random laughing guys who show up, then she goes and kills a bunch of people. There's nothing more to it than that, except lots of the dud camera angles and effects that student filmmakers always put into their movies to try to disguise a lack of storyline. The whole thing feels like it was shot in the street with a camcorder on a single evening, with no script either.
The only, and I mean only, interesting thing about this production is that it predates the current Japanese wave of ultra low budget gore flicks in which high school girls have machine parts attached to their bodies and fight off OTT enemies with body parts flying across the screen, a la MACHINE GIRL. It probably served to inspire them, but as it stands it's a complete dud.
