I give it 5 stars wholly on LEE JONG SUK's acting, I man I loved his acting ,it showed the versatility of the actor, i always saw him in a positive role ,but this was so well, i mean it was purely evil, hats of to him, and yeah they went bit too far away with the whole female torture i mean yeah he was a psychopath but no women power was justified. it was a saga o women neither any other killings by the evil kim was shown apart from women , so yeah the plot it could have been better, and all the suspense and power of kim family was greatly portrayed.
