Okay, so I was in the mood for some good thriller movie from Asia and decided to check this movie out, plus it has Su-Ae in it who is a pretty and yet elegant actress. So I thought it wasn't going to be a big waste of time, in fact by watching the trailer I thought this movie was going to be similar to the movie "P2". Which is another thriller and has a smart female protagonist that uses her wits without going overboard to try and survive the nightmare from a crazy stalker. Anyways I thought it was going to be like that movie. And from the trailer it looked pretty intriguing although nothing much happen in the trailer, which is for the most part a good thing in this case. This movie has suspeneful scenes but unlike "P2" a lot of the parts takes place outside of the building the protagonist resides in. Su-Ae played her role in a very balanced way where it didn't come off like a annoying victim in a movie. Although there are annoying character in this movie but it's intentional, and yet very annoying, luckily she isn't one of them. Yoo Ji-Tae also does a fine job playing the villain, he always seemed to play the psychotic character pretty well and it's the same for this movie as well. Although this movie is full of incompetent and annoying character that contantly get in the way, I did like the stalker helping fight another stalker aspect of it. Overall this was a pretty good Korean thriller that is put together really well near the end.
