Well seeing the few bad reviews regarding this from Korean netizens in aspect to the portrayal of women I was not so sure of how this will actually fold out. Surprisingly the plot was intriguing and it actually kept me glued to the screen. This obviously won't be everyone's cup of tea. The tag 18+ almost seem not enough for the violence shown in this movie. The first scene of this made me almost puke. Other than the obvious violence in the film I've got to say Lee Jong Suk makes one fine ass villain. Damn he was scary n this film.
If you are into thriller and ok with grotesque portrayal of killing, yeah this is a good movie for you.
