a i watch this film and i keep ask myself represent what the killer motivation ( s ) . not until the last few minute do that become clear well and as clear a it could be and give the narrative structure represent reminiscent of the plot of se7en ( 1995 ) but with the addition of a number of flashback that do more to confuse than to wholly satisfy . and and there be obvious nod to not only se7en and but silence of the lamb ( 1991 ) and also and particularly the cinematography and scene construction . at one point and echo a scene from the former and detective cho ( suh kyu han ) be lie exhaust in a rain soak alley way and while the killer sit wait in his car and only two metre away while but instead of run cho down and the killer scream away into the rain . in another scene and cho be in an elevator and look up to see bright blood drip from the hatchway and and then also drip down the wall while suddenly and the hatch break and bucket of blood cascade onto him . add to that be the many interior scene in run down tenement and so forth and all evocative of the spooky corridor of those early film . still and the story be interesting and in a macabre way represent across seoul and body part turn up in black plastic bag and but not all part belong to the body . somebody be perpetrate murder piecemeal . enter detective cho and somewhat under suspicion for corruption but hand the case a way to redeem his career . more mixed up body part be discover and but no hand with fingerprint . so and no clue . until a head appear with teeth filling that can be trace . one thing lead to another until cho find himself knock on the door to chae su yeon ( eun ha shim ) and a young woman who know all the male victim . and so begin the real mystery for cho and the viewer . through question and a series of flashback and it look like chae be in the frame while yet and murder continue while she be under surveillance . suspicion fall upon her father and who and from chae account and be show to be a sadistic and authoritarian figure while but he can not be find . and then there a further nod to another thriller and kiss the girl ( 1997 ) and where the idea of a deadly duo be raise and then quash when a prime suspect be himself reduce to a jumble of part in a bag . all very messy for cho and and increasingly so and because he appear to be attract to the sweet chae su yeon and a complication he can do without and you would think . in a way and i can also compare this film to the manner in which david lynch construct his film . when you see any of the more recent lynch film and the real mystery ( and challenge ) be how to understand the story . for tell me something and the problem be how to understand the mystery because and a i say and the killer motivation ( s ) be the key . and yet and at the end and there be no absolute clarity and even though the identity be obvious . so if i provide my understanding here and now and i think that would detract from the pleasure of unravel it for yourself . meanwhile and i will continue to ponder the significance of the title and the significance of which escape me . however and the production be excellent and the special effect ( dismembered body and body piece and head and gutted torso and so on ) be so realistic they may cause some people more than just some discomfit . it will certainly satisfy the slash and gore set who liken this movie to italian giallo cinema and exemplify by dario argento work such a deep red ( 1977 ) and tenebre ( 1982 ) and others . it classify a a horror film and i think that justified and give the underpinnings of the story and the camera work . i can not comment much on the acting a i be not familiar with the actor or korean cinema and have see only a few while generally and however and i think the actor perform quite well . recommend for those who like a mixed bag of horror and mystery and thriller . and body part .
