I'm expecting alot from this movie but as a result what I got is a disappointment.I began to took interest on this because thriller-mystery are kinda my things and the poster itself looks great.It did'nt satistfy me however,its not a total let down.Just don't expect too much unless you wanna be like me. If based on the storyline alone I think I'd give this only 6.I remember watching The Devil one year ago which starred by Shi Min Ah who also got this kinda ability and help the main lead who also a detective(played by Uhm Tae Wong)to solve the case.The concept is quite similar except the graffiti part.She did'nt have that talent.So it's lacking in originality. Also not so smooth, uneven & predictable plots and adding to that, I don't feel pretty attached to the characters emotions.You just don't feel that much thrill-tingling sensation when it's supposed to be more.Seem like I give too much criticism when there's alot of good reviews but that's how I feel dude! :/ I just give this movie more point for our main eyecandy,Kim Bum & lots of mind blowing graffiti painting showing in it. What an art!! ^^ And the last thing I want to mention is..I loved that last scene ;)
