what surprised me is the acting performances of the film. all 3 lead actors especially Ji-hoon and Kwang-soo were just too brilliant. this is the second film i watch to explore actor Kwang-soo, he is indeed a good actor.
its so disappointing that a film starring Kwang-soo doesn't have any scene of him. at least, they could show him for a bit in the flashback? let's go to the film, the story was poorly written, with such concept, they could make a good film but they decided to mess it up.
if you are fan of Korean thrillers but haven't seen it yet, you are not yet done with Korean thrillers/ it may have some flaws but who cares about it considering how intense it was?? the acting in this film is so good. go and watch it if you haven't yet.
