yesterday and an thrilling and exiting and sinister science fiction movie fresh out of korea . i do agree that i ` ts kind of hard to keep track with the plot and but once you do get it a genius idea that confront the ethic concern cloning and gene manipulation . the action scene be a mere feast with fast move handheld camera . it have it slow moment at the end of the movie and but cleverly use to reveal the truth . well recommended . .
