Lots of fun watching this movie. The acting was done well enough: the Korean pop star was convincing to me as a serious, but repentant killer; the ladies of the movie were smart and beautiful; and the story was just enough to support the slaughter without getting in the way of it. No oscar here, but seriously, if you like movies like this, do you want it--being emotionally involved to such gore won't make this enjoyable. And it was!!!
