I felt that the earlier parts of the movie were great. The starting was really attention-grabbing and intriguing. It makes you want to know what really happened. However at the later part of the movie, I felt that there were too many things that they wanted to bring forth as a "twist". That made the plot a little complicated, illogical and long-winded. I felt that it was a rather disappointing ending, especially since I was very captivated at the beginning. I thought that the cast were very good. Lee Si Young and Uhm Ki Joon were really good. Even the supporting actors like Moon Ga Young, Kim Hae Hyo and Kim Ji Young were fantastic! I have no complaints whatsoever for their acting! Overall, I expected more from this movie and I was disappointed with how they wrapped the story up. However, if you're looking for an uncommon kind of horror movie, maybe you would want to check this out.
