if you consider yourself a horror movie fan and chance be you have see hideo nakata ring and dark water . theyre superb and and ring make it way smoothly into hollywood ( maybe dark water will be adapt soon too . ) . while ring be almost 100 % pure heart pounding and nerve breaking and a tale of two sister be both nerve breaking and mind twisting . along with the other i consider this korean flick a brilliant and smart end horror movie . the only flaw this movie have be some consider it first 20 minute rather slow . it actually typical with korean and japanese movie . i consider it carefully plan rather than slow and think of it a calm moment before the storm . with thorough introduction of character and imho viewer will get involve more intimately with the character and one of korean and japanese movie strongest point . like ring and a tale of two sister doesn not overdo ghastly appearance . rather they let our mind do the intimidating job itself . that way it scarrier and horrifyingly classy at the same time . i would not be surprise if hollywood remake this movie after bring ring and grudge or ju on over ( this flick be not that good by the way and i rate it 5 . 5 ) . don not miss it .
