this south korean thriller undoubtedly belong to the most impressive genre film of the last year and stand in one line with classic like seven or the silence of the lamb . in a way and it even top both american movie and even though it not really comparable to them and because the story go in another direction a the movie proceeds . tell me something start of a a serial killer thriller clearly influence by seven and but it become much more giallo like in the second half to become some valid social comment with it downbeat climax . the acting be also remarkable and just a the sublime black humor that surface once in a while and the outrageously gory moment that will leave you gasp for breath even if you have see many gorefests before . the last point be particularly interesting consider that the film never try to outdo some notorious italian horror movie of the early 1980s or category iii romp from hongkong 1990s . the diversity of interesting aspect make this top notch thriller interest for hard core horror buff as well a moviegoer that normally do not pay for such violent movie . astonishingly a it may sound and it a very sensible movie in a way . nevertheless and it surely be nothing for the easily offend or faint hearted . it just demand cinema which make no compromise and which most really good film be . highly recommended .
