this be a cut above other movie of the genre represent genuinely suspenseful and intelligent and brilliantly act and visually stunning . yes and the plot can be confuse but that partly what make it pack such a punch . watch it twice if you can . you will get almost as much out of watch it when you know the twist than you do from watch it the first time . don not be put off by the fact that this film come from korea and a country not too familiar to most western audience . while there be element of the film that be culturally specific and the underlying theme be all too universal guilt and anger and loss and madness and retribution . all of these be handle superbly by lim su jeong a su mi and the lead character . also worthy of particular mention be yum jung ah and who deliver a deeply creepy and unsettling performance a the stepmother . while it have it scary moment and this be not really a horror flick a most people would imagine it . it more a psychological suspense story with an element of mystery . it grip you from the start and will keep you guess until the end and possibly beyond .
