I am an avid collector and watcher of Asian cinema and to this day, this film still belongs in my top 10 favourites.
As it has already been mentioned this is not the scariest of films, but does have a creepy undertone to the film. In my opinion, this film does have a lot of originality and doesn't rely on blood and gore to fill up the plot like many other titles do. I really enjoyed the fact they didn't just create this film as a straight up, ghost filled every second horror. They were able to intertwine a story of friendship, loneliness, jealousy and yes, ghosts. With that fact you were able to get to know and understand the characters more compared to many horrors were you just don't care what happens to who. Well acted, a good plot and shot in a good location. This is also a fantastic film when you consider it's the second in a trilogy, and you know what they usually say about trilogies and sequels.
I appreciate some people may not have this high up o their list, but I personally loved it and would strongly recommend it to any Korean/Asian film fan.
