the idea is not original. if you have seen such kind of story before and you would know what the ending would come out after watching for the first twenty minutes. the script and the positioning of the actors and the screening is too obvious. if you haven not seen such story before and it is definitely a good experience and you will enjoy the twist at the end. do not forget to watch it again after you know the truth and you will even more enjoy the plots. even though i have a right guess at the very beginning and i still couldn not help stick on my seat till the end. conclusion represent a must see. this one from korea is better than any recent movies of the genre from japan. forget hollywood. don not miss it.
